When a man is found dead in an underground car park after a horrific flood, police suspect he simply drowned. PC Joanna Marshall, played by Sophie Rundle (Peaky Blinders), leads an investigation seeking to determine if more sinister foul play was at hand.

The show examines the effects of the flood on the town’s community, uncovering secrets, damaging reputations, and threatening some resident’s fortunes.

Sophie Rundle is excited to step into Joanna’s shoes, commenting: “I am really thrilled to be joining After the Flood. Jo is a brilliantly bold, compelling protagonist. The story is sharp, intriguing and articulate about the climate crisis and the impact on the communities it is directly affecting. There are so many people I’m really looking forward to working with on this project, I can’t wait to get started.”

The show also features Philip Glenister (Life on Mars), Lorraine Ashbourne (Sherwood), Nicholas Gleaves (The Crown) and Matt Stokoe (Cursed) in supporting roles.

“I am always excited to announce a new project but After the Flood in particular tops all of the others due to its ambition and the characters,” series writer Mick Ford told ITV. “The cast are fantastic, and I am thrilled with how perfect each cast member is for their role.

"ITV have been brilliant throughout the writing process allowing us the time to craft the scripts with care which is rare and brilliant. Plus working with Quay Street Productions for Nicola and Richard is so special – because they and their teams are so special, and I feel truly honoured. It is going to be great seeing everyone getting into the story and seeing it come to life – and then there is the flood!” 

Filming in Manchester, Derbyshire, West Yorkshire and Teeside will commence in February 2023.
