The second series of After the Flood finds newly promoted detective Jo Marshall on the trail of a baffling murder investigation. As tensions simmer in Waterside amid the rising threat of moorland fires and the subsequent risk of further flooding, a body is discovered in bizarre circumstances. Jo's race to stop the killer will put her in opposition to dark, influential forces within the town, and ultimately take her on a much more personal investigation. One that will require her to operate in secret if she is to have any hope of rooting out the corruption that has blighted the town's police force - and her own family - for decades.

After the Flood is set in a town hit by a devastating flood. When an unidentified man is found dead in a lift in an underground car park police assume he became trapped as the waters rose, and as the investigation unfolds PC Joanna Marshall becomes obsessed with discovering what happened to him.

How did he get in the lift and why does no one know who he is?

The floods threaten to expose secrets, and fortunes and reputations are at stake. But how far will people go to protect themselves?
