Violent psychopath Tim Cook, dubbed 'The Leopard' by the press, escapes from custody on a hospital visit, having vowed to get Regan, who put him away. He is sheltered by ex-cellmate Ian Pinder in a house belonging to Pinder's gay uncle but after freaking out and attacking Uncle goes on the run and hides in the woods. Regan and Carter lead the Sweeney in a manhunt which leads to a shoot-out.
