Watch her disappear

The body is found by the river, near a spot popular with runners. With a serial rapist at work in the area, DI Zigic and DS Ferreira are initially confused when the Hate Crimes Unit is summoned to the scene. Until they discover that the victim, Corinne Sawyer, was born Colin Sawyer. Police records reveal there have been violent attacks on trans women in the local area. Was Corinne a victim of mistaken identity? Or has the person who has been targeting trans women stepped up their campaign of violence? With tensions running high, and the force coming under national scrutiny, this is a complex case and any mistake made could be fatal.
