Carl is a security officer, watching the local streets on a bank of CCTVs. A kindly man he is unable to prevent a female suicide and, when he reports a group of drug pushers he is rebuffed by a patronizing policewoman who claims the force are too busy to investigate. He enlists his colleague Lee to frame them but Lee only steals their money and, after a visit from teen-aged daughter Kelly, upset following a row with his unfaithful wife Sandy, Carl finds that the criminals have abducted Lee and mean him harm. With no official back-up Carl puts himself on the line to effect justice.
