Matthew Graham Jesper W. Nielsen 18 May 2017 14 May 2017

Kat and Alfie Moon arrive in the sleepy Irish village of Redwater on a quest to find Kat's long-lost son. They uncover a secret that the village wished had stayed buried - the inhabitants are still recovering from a tragic boating accident that happened over 25 years ago.

In summer 1994, a boating accident causes the deaths of Iris and Aoife (known as Mouse). Lance rescues the young Dermott, Andrew and Kieran.

21 years later, Kat and Alfie arrive in Redwater as Kat believes her son is there. She meets Andrew, who she believes is her son. Andrew's grandmother, Agnes, is immediately suspicious of the Moons and Alfie warns Kat to wait for the right time and make friends first. Kat confides in Lance that her son was taken away from her in 1983 and she believes he is in Redwater. Alfie starts having hallucinations because of a tumour on his brain. Alfie then learns of the Redwater Tragedy from Dermott, who is now a Catholic priest.

Lance tells Agnes about Kat and Agnes immediately says that she should not be told the truth as it would unravel everything they have built. Kat asks Andrew about his life but Lance warns him to give the Moons a wide berth.

Tommy gets stranded on a cliff but Alfie helps him up. Alfie gets stuck but Dermott helps him to the top.

Kat admits to Alfie that she is scared of seeing how disappointed her son would be in her.

Lance tells Dermott that Peter and Iris are not his real parents - but Kathleen is his mother. He wanted to tell him the truth but Agnes made sure it was kept secret. It is revealed that Iris lost a baby in London and brought Dermott back as her own and Peter does not know the truth. Dermott says he will think about things.

The next day, Lance goes for his morning swim in the sea and Adeen takes his horse for a ride without him knowing. Dermott approaches Lance, who says that they can work through this together. Dermott offers Lance a sacramental wafer, then drowns him while flashing back to Iris's death, showing Dermott deliberately letting go of Iris's hand, causing her death. He prays for Lance and then forgives him.

A death in the village has huge ramifications for the wider family and with Kathleen's only ally now dead, she seeks help from anyone who can help her find out the truth about her son.

Adeen finds Lance's body, while Dermott enters an empty confessional to confess his crime.

Agnes' daughter Eileen and grandson Kieran return to Redwater from the United States for Lance's funeral and Kathleen quickly realises that Andrew is not her son while talking to Eileen. When Agnes confronts Kathleen, Kathleen explains that she did not know she had a son as she had passed out during labour and he was taken away from her before she regained consciousness.

Bernie is suspicious about the circumstances surrounding Lance's death, so has Adeen's mobile phone sent to the forensic's lab to have photos she took of the scene enhanced.

Lance's will is read and Agnes is devastated that he has left everything equally to Roisín and Eileen - and nothing to her.

Episode 6[]

Matthew Barry Jesper W. Neilsen 22 June 2017 18 June 2017

Bernie pieces together the truth about Lance's death. Agnes shuts Peter down when he threatens her. Alfie is left fighting for his life. Kathleen discovers Dermott's secret.

Bernie questions Dermott over his whereabouts on the morning Lance died. He says that he was in the church and he last saw Lance in the pub the night before.

Kieran tells Bernie that he remembers Dermott letting Iris die on the boat and suspects that he was involved in the Cois Dara fire. Bernie then asks Kathleen about the last time she saw Lance and Kathleen wonders if Bernie suspects that something has happened but Bernie denies this.

Padraig finds Adeen crying by the side of the road and later takes her to get an emergency contraceptive pill because she had sex with her friend Jimmy. Afterwards, Adeen tells Padraig that she saw Andrew and Kieran together and asks if Andrew is gay, to which Padraig says no.

Dermott takes Alfie to the hospital for an operation, where the doctors tell Alfie that his recovery could take weeks, so he will be unable to go home as planned. Alfie asks Dermott to find Kathleen and bring her to the hospital.

Roisín and Eileen find Peter and bring him home. Roisín tells Eileen that he is an alcoholic. Peter confronts Agnes over swapping his baby for Dermott but Agnes says that his affair with Roisín caused the baby to die and it is his own fault. She warns him not to reveal the truth, otherwise Eileen will discover that Mouse died because Iris discovered the affair and turned to drink before getting in the boat that fateful night and therefore Peter and Roisín caused the death of Eileen's daughter. Agnes insists that Dermott is still Peter's son and tells him not to lose him.

Peter tells Bernie that Dermott was the last person to see Lance alive as they had arranged to meet that morning. Bernie then sees CCTV footage of Dermott deleting her emails while she was giving birth.

Kieran tells Andrew that he does not want to break up his family, so ends their affair and says that he will return to New York. However, Andrew later visits Kieran and they kiss.

Roisín and Padraig argue about him not making sure there is money in their bank account for the morning and when he asks why she did not leave him years ago, she says that she did.

Agnes tells Roisín that because Peter is drinking, Eileen could find out about their affair that resulted in Mouse's death. Agnes asks Roisín to help her send Eileen back to the United States and shows her a letter from Lance's son in Manchester, asking about the will.

Bernie sees Dermott with Kathleen on the beach and Kathleen tells Dermott that Bernie was asking about him. Dermott sees the garda arriving so takes Kathleen in Peter's boat, saying that they will try to find the whale that was recently seen off the coast. Bernie shouts at him to stop and calls the coastguard. Kathleen asks Dermott if he did something to Lance. He accidentally crashes the boat into a rock and Kathleen is thrown into the water and then cut by the propeller. Dermott gets Kathleen out of the sea but there is nobody around to help.

Unable to wait for Kathleen, Alfie has his operation. He loses his pulse and the medical staff start to resuscitate.


Mo Harris tells Kat Moon that Harry Slater had left her some money in his will. Alfie Moon finds out and tries to convince her to use the money to make a fresh start after the divorce. She takes the cheque from Mo and later rips it up in front of Alfie, insisting that it doesn't change the past. Stacey Slater reveals to Alfie that their rent is increasing and Kat is struggling with money. Kat is devastated and she writes a letter to the solicitors about receiving all the remaining money from Harry's will and intends to post it the next morning. The next day, Kat changes her mind and throws the letter away but Mo retrieves it and posts it on her behalf. Mo then transfers the money into her own account. Kat later finds out about this, and then, after burning the money, falls into depression and tries to kill herself. 

This causes Kat to re-evaluate her life, so she visits the nunnery where she gave birth to Zoe Slater to seek some answers. Sister Ruth remembers Kat going into labour and they talk about the past and the future. Unknown to Kat, the nun checks their records and reveals that Kat also gave birth to a son. Later, a content Kat returns to Walford and tells Stacey and Alfie that she has finally made her peace with the past and is no longer willing to let Harry control her. After a night together in central London, Kat and Alfie decide to buy a scratch card. They win a million pounds and begin to make plans to move to Spain so Kat can be closer to Zoe. However, Alfie discovers that he has a brain tumour and he worries about going. He then ask Sonia Fowler if it is safe to fly and she advises against it, so he decides not to tell Kat. Kat and Alfie then leave with Tommy, Bert and Ernie Moon to live in Spain.

They return eight months later as Kat isn't enjoying Spain - Zoe has told her yet again she wants nothing to do with her. She is surprised when Sister Ruth visits her and reveals the truth about her secret son, Luke, to her. After Kat argues with Mo and Charlie Slater about the secret son after discovering that Mo knew, Charlie has a heart attack and dies, leaving Kat devastated. Belinda Peacock returns and blames Kat for Charlie's death. Alfie later tells Kat that he has a brain tumour but assures her that it is benign. Kat, after learning that her sisters do not want her at Charlie's funeral, visits Charlie's body to say her goodbyes, and vows to be at the funeral to make him proud. However, on the day of the funeral, Kat notices that Stacey is ill so stays with her at the Vic to say her goodbyes to Charlie. At the wake, she makes up with Belinda. She confesses to Belinda about Luke, and Belinda says she remembers Viv taking her on a trip to Redwater, Ireland, and noticing a couple staring at them with a new-born son, and she thinks it might be where Luke is. Kat tells Alfie, who wants to start planning a way to find him.


The spin-off show was announced on 4 April 2015 by Dominic Treadwell-Collins and was revealed to be set in Ireland.

Speaking about the new drama, Dominic said, “In the next few weeks on EastEnders, viewers will witness several huge twists for Kat and Alfie Moon that will change their lives forever. Now is the perfect time to take two of EastEnders’ most beloved and enduring characters out of their comfort zone as they head to Ireland to search for answers to some very big questions… My team here are very excited about creating a whole new drama that stands apart from EastEnders while taking our style of storytelling to a place of stories, myth, secrets and immeasurable beauty.”

Charlotte Moore, Controller of BBC One added, “Life is anything but dull for favourite EastEnders couple Kat and Alfie as they embark on a new life in Ireland in this exciting drama series. Rest assured, their rollercoaster isn’t set to end any time soon.”

Speaking of their new drama, actor Shane Richie said, “Both Jessie and I are absolutely thrilled to be given this amazing opportunity. To have a whole drama focused around Kat and Alfie is a huge honour for us both and we just can’t wait to start filming.”

Jessie Wallace added, “I have always loved working on EastEnders so when I heard of this new drama to take Kat and Alfie outside of Walford, I couldn’t believe our luck. To be exploring the next chapter for Kat as well as working alongside my best mate, Shane, is a dream come true and a huge compliment.”


Shane Richie said that, as Redwater is a stand-alone series, there is no reference to the EastEnders locations of Walford, Albert Square or The Queen Victoria pub. Alfie does however mention that he once worked in a pub, being the only reference to the character's time in EastEnders.

Kat and Alfie's twin sons, Bert and Ernie Moon, do not appear in Redwater, because Dominic Treadwell-Collins knew that having two small children in the series would have "limited Kat and Alfie and they wouldn't have been able to do as much". He did reveal that they were originally due to appear but, "suddenly you ended up having storylines about who is looking after the twins and on a show like this we needed to tell other stories". It was confirmed that Kat and Alfie have only left them for a few weeks and check on them during the series.

It was announced on 30 April 2017 that EastEnders would make a "subtle reference" to Redwater in May, "in a bid to keep the two shows in the same universe", revealing that Kat and Alfie have arrived in Ireland. The reference was made in the episode shown on 16 May 2017, two days before Redwater's UK premiere, in which Kat's relative, Stacey Fowler receives a postcard from the pair. Redwater viewers noticed a continuity error in relation to this, as the flashback scene at the start of episode 1 is set in 1994 and then the story continues from "21 years later", meaning it takes place in 2015 - though Kat and Alfie left EastEnders in 2016 which is when Kat discovered that her son existed and Stacey received the postcard from Kat in EastEnders in 2017.

Kat refers to a postcard concerning her son dated from December 1983, though the EastEnders timeline gives her son's birth as being in February 1984. Additionally,

Adam Postans from The Daily Mirror said that the details in EastEnders of how Kat discovers her son is in Redwater were either "forgotten or abandoned" as they are different in Redwater.
