Copkiller (l'assassino dei poliziotti)

Fred O'Connor (Harvey Keitel) is a dysfunctional police officer who co-owns a secret luxury bachelor pad with his partner, bought with dirty money. The city is going through a series of cop killings and paranoia is rampant, though O'Connor doesn't really seem all that concerned at first. He becomes a little jumpy when he finds himself being stalked by a mysterious weirdo (John Lydon), and positively freaks out when he turns up on his doorstep claiming to be the cop killer. O'Connor doesn't believe him but is panicked all the same, as his whole secret life is at risk of being revealed, so he does the logical thing - he keeps him prisoner.
