Gritty action escape thriller following a rag-tag group of cons' attempt to break out. Frank Perry (Brian Cox) is serving a life sentence without parole when he hatches a plot to escape from prison in order to reconcile his relationship with his daughter who is in a critical condition after a drugs overdose. Gathering an unlikely group of fellow convicts around him, including the prison's drug dealer Viv (Seu Jorge) & silent muscle Lenny (Joseph Fiennes), Frank, realising he's still short on bodies, is soon forced to take along a number of the less stable elements of the prison population, with all the risks that they bring.
