Trust  is made by Nicola Shindler’s Red Production Company and stars Jodie Whittaker as a nurse, who, out of desperation, steals the identity of her friend, a former hospital doctor, and starts afresh, working in Edinburgh. But she lives with the constant threat of being discovered, not only by her colleagues but by someone else hot on her trail.
