Season 2 Story: Jo Marshall’s New Investigation
The second season picks up with detective Jo Marshall, played by Sophie Rundle, in a new role. She has been promoted from Police Constable (PC) to detective. A new and strange murder case happens in her town, Waterside. The town is still dealing with the effects of climate change, this time facing the threat of moorland fires which could lead to more flooding. While investigating the murder, Jo finds herself fighting against powerful people in the town. The official description says the investigation becomes “deeply personal” for her. She will have to work in secret to try and stop the corruption that has hurt the local police and her own family for many years.
