Amy Harris (Elaine Cassidy) loves being a cop. Young, popular, bright and ambitious she thrives on everything the job throws at her. The routine arrest of a young Asian man, Rakesh Homaine, turns into a murder investigation when Amy finds him alone in the police interview room beaten, battered and drowned in his own blood. The Independent Police Complaints Commission (IPCC) storm the building, locking-down the entire station. No one is allowed in or out, all phones are confiscated and the building becomes both a crime scene and a prison for the working policemen and women. Suddenly every officer is a murder suspect. And when Amy’s uniform, drenched in blood from the scene of the crime, goes missing, she realises that she is being framed for murder by her fellow officers. In the claustrophobic confines of the station, isolated and alone, Amy sets out to find who really killed Rakesh in order to uncover the truth and save herself. She turns to her best friend Jo (Christine Tremarco) for help. But can she trust her or any of the other officers that she has previously considered to be her friends? Working against the clock and desperate to clear her name, Amy uncovers a level of endemic corruption in her station that forces her into a decision that will change her life forever…
