For Her Sins is a new four-part psychological thriller about a successful lawyer who befriends a local woman, but she has darker intentions and her new friend is secretly plotting against her.

The plot of the series teases: "Laura and Emily soon become firm friends, and Laura is relieved to finally have someone to talk to about her anxieties around motherhood — but what she doesn't realise is that she and Emily are connected by an event in their past, and Emily's arrival in her life was no accident..."

The Channel 5 thriller features a lot of great talent, mostly from the world of soaps, who are all playing characters in the Adrian McDowall directed series.
