Sophie Rundle plays Jo

Who is Jo? A police officer who is expecting her first baby. Jo has her sights set on becoming a detective like her dad, who died three years ago, and when a dead body is found in the town, she sees an opportunity to prove herself.

"Jo's commitment to solving the mystery and protecting her town is dogged and unwavering. However, although her intentions are pure, her adherence to the rules is less so – and her determination to get to the truth often gets her in more trouble than she anticipated."

Where have I seen Sophie Rundle before? She's best known for Peaky Blinders and Sally Wainwright dramas Gentleman Jack and Happy Valley. You might also have watched her in BBC thrillers The Nest and Bodyguard, and Sky period drama Jamestown, among others.

Lorraine Ashbourne plays Molly

Who is Molly? Jo's mum. The pair are extremely close. "Family has always been the centre of Molly's world, but with her husband gone and Jo settled with her own family now, Molly has found herself feeling a little lost – although she'd never admit to this publicly."

Molly is also a key voice in the community and bangs the drum for better flood defences for the town.

Where have I seen Lorraine Ashbourne before? She starred in James Graham's BBC drama Sherwood. You might also have watched her in Netflix's Bridgerton, season 2 of ITV crime drama Unforgotten, BBC comedy Alma's Not Normal and BBC One's Playing the Field.

Matt Stokoe plays Pat

Who is Pat? Jo's husband, who is a detective with the Serious Crime Squad. He spends much of his time telling a very pregnant Jo to put her feet up, words which often fall on deaf ears, and they clash over the course of the series.

"He loves his wife Jo deeply, but he's overly protective of her – always treating her with kid gloves, wrapping her in cotton wool, and he would much prefer it if she wasn't in the police force."

Where have I seen Matt Stokoe before? Stokoe, who is Rundle's husband in real life, appeared alongside her in Jamestown. He also played Raoul Moat in a 2023 ITV drama about the hunt to catch him.

Philip Glenister plays Jack

Who is Jack? A local property developer who moved to the town 30 years ago. He's overseeing the construction of a new eco housing estate.

"Charismatic, persuasive and well-liked, Jack enjoys the status of being a big fish in the town he now calls home. Things are going well for Jack, but when one of his buildings becomes the centre of the police investigation, Jack inevitably finds himself in the spotlight."

Where have I seen Philip Glenister before? He's best known for police procedural Life on Mars and its sequel Ashes to Ashes. He also appeared in true crime drama Steeltown Murders, which aired on the BBC last year, Julian Fellowes's Belgravia, Sky's Mad Dogs and BBC drama Clocking Off, among others.

Jacqueline Boatswain plays Sarah

Who is Sarah? The Chair of Planning on the council, who has her sights set on Westminster. But "all of that is put at risk when the flood hits Waterside, and Sarah's response to it comes under intense scrutiny".

She attended the same school as Molly, but "often found herself on the fringes". Sarah also has a close relationship with Jack, which her husband isn't a fan of.

Where have I seen Jacqueline Boatswain before? Most people will know her from Hollyoaks and Grange Hill.

Jonas Armstrong plays Lee

Who is Lee? A mysterious hero who had a "painfully troubled upbringing", which led him to a young offender's institute when he was 16. From there, he continually found himself pulled back into a life of crime.

"He ultimately wants to do the right thing, but by this point in his life, that simply isn’t an option anymore."

Where have I seen Jonas Armstrong before? Many viewers will recognise him from ITV crime drama The Bay, BBC drama Robin Hood, Channel 5 thriller The Drowning and BBC drama Floodlights.

Nicholas Gleaves plays Phil

Who is Phil? A sergeant who is the "warm, stable leader of the community, taking charge in the wake of the devastating floods". He has become a surrogate father figure to Jo following her father's death.

Phil is married to Sarah and the pair of them have fostered lots of children over the years, "which is partly why he’s never risen above the rank of sergeant - instead putting his focus into supporting his ever-changing family".

Where have I seen Nicholas Gleaves before? His credits include Coronation Street, Sally Wainwright's detective drams Scott & Bailey, the 2019 revival of The Demon Headmaster. Playing the Field and Kay Mellor's The Chase.
