Cath Hardacre is a good nurse. Caring and hard-working, she does her best for everyone in the cardiology ward she works in. However, when she raises her concerns about the standards slipping in the hospital, Cath’s world takes a turn for the worse.

After being sacked for whistle-blowing, Cath turns to her best friend Dr. Ally Sutton, who is leaving her life as an A&E doctor and emigrating to New Zealand with her new husband. At a drunken party Cath finds Ally’s discarded paperwork and makes the desperate decision to take a second chance at life – by stealing her best friend’s identity…

Cath, now calling herself Ally, accepts a job at a failing emergency department in Edinburgh and embarks upon a new life with her young daughter Molly. However, with her good-for-nothing ex-partner Karl, played by Earache’s wonderful Blake Harrison, trying to spend time with them and a journalist chasing her about the issues at her former hospital, how will Ally cope with leading a double life?

See Blake in “Trust Me” on BBC1 from 8th August.
