After The Flood plot 

After The Flood follows life in a town struggling in the aftermath of a major flood that has wrecked the community. As the clear-up starts, the body of an unidentified man is found in a lift in an underground car park and the police quickly assume he was trapped by the rising waters. 

However, as the investigation unfolds, pregnant PC Joanna Marshall (Sophie Rundle) becomes obsessed with finding out what happened to him, and it seems the floods will expose long-buried truths.

After The Flood cast — Sophie Rundle on playing PC Jo Marshall 

Sophie Rundle, who plays determined cop Jo Marshall in After The Flood, says: "I opened the front page and started reading and I kept going, ‘Is that me? Is that my character? Do I get to do that? That is so cool’. Especially for someone in my casting bracket. I’ve done a lot of corsets and a lot of holding babies and mooning after someone in the background. To be doing the stunt and not just witnessing it was so exciting. I think it is so clever of Mick Ford to write that as the introduction for your protagonist. This is the world. These are the stakes. Here she is. She’s in the water. She’s saved the baby and she’s pregnant. Boom. You’re in. How could you not watch that? 

"We were up in Stockton-on-Tees for a week filming the flash flood, and it was like being on a school trip. Before that we had been filming in and around Manchester, so this was the only time we all went away somewhere. We were all giddy and excited. It is where they train all the emergency services. There’s this water course and they have control of the speed and the scale of the water. They had all these big strapping six-foot lifeguards in all their emergency gear stationed along the water course who were lovely. They said, ‘If you fall the water is going to take you but don’t worry, we’re going to save you.’ Luckily, I didn’t ever stack it, so they didn’t have to save me. It was a really exciting moment as an actress and as a woman in this industry to be the hero reaching out for the baby dressed in all my police gear with the rain going. The water was really strong, and we were in and out of it all the time. On the last day I realised my hand was shaking because I hadn’t eaten anything. I was so pumped from the adrenalin. It wasn’t a normal day at work where you do your lines, and you go home. It really made the job for me."

Philip Glenister on playing Jack Radcliffe

Philip Glenister plays property developer Jack Radcliffe in After The Flood. He says: "He’s a bit of a Jack the lad. He’s a big fish in a small pond. He’s never married or had children. To be that age and to go through life like that probably makes him a self-centred, selfish sort of human being. He’s still a bit of a lothario, God forbid, but he does have a good side to him. I think that’s important to say. He does have a caring side. That side is wrapped up in his business dealings, but he has turned his work into something that can be environmentally friendly as well. 

"He’s got a lot at stake on with the Uplands eco housing project. The bottom line is if this Uplands project gets flooded then he loses his entire business. So, it’s important for that to work. It’s just getting the cash flow and all the red tape that goes with it. Then there is everything else that is going on within the town and there is quite a lot going on. Jack comes in and out in his ‘ecologically friendly’ Range Rover! And his V8."

"Working alongside Lorraine Ashbourne was just brilliant. We laughed so much. One day we were up doing this scene on a hill and although the sun was out it was freezing. We’re sitting there supposed to be eating chips and the chips were also freezing. Then we had to have a little kiss at the end and we both had chip teeth. Sorry, I’ve got a bit of chip in my teeth! It was good fun. She’s great Lorraine. She’s just one of nature’s life forces. She’s funny. She’s smart."

* Philip Glenister shot to fame playing DCI Gene Hunt in the BBC1 time travel series Life on Mars and Ashes to Ashes. He’s also starred in Clocking Off, Roger Roger, Hornblower, Vanity Fair, The Other Boleyn Girl, Calendar Girls, Cranford, Mad Dogs and Belgravia

Jonas Armstrong on playing Lee Ellison in After The Flood

Jonas Armstrong, who plays hero Lee Ellison in After The Flood, says "When you first meet Lee, he is running down the embankment. A baby is being swept away by the current and the flood. Without thinking he goes on instinct and just plunges into the water risking his own life essentially to save this infant. We presume this man is dead because of the ferocity of the flood and then right at the end of episode one you see him washed up on the embankment further down. Lots of hours have passed. He’s unconscious. He wakes up. There are police sirens. He sees the activity going on, he’s injured. Rather than go towards the town, he makes a decision to go the other way. I can’t tell you much about his history, but he has a chequered past."

"ITV has 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 honored. It is going to be great seeing everyone getting into the story and seeing it come to life — and then there is the flood!”
