The head of a trucking company is killed before eyewitnesses, and McCloud's girlfriend is the culprit.

On Christmas Eve, an assassin stalks McCloud, a spurned mistress attempts suicide, a sidewalk Santa turns mugger, junkies raid a hospital pharmacy, Chris's newspaper organizes a party for orphans at Westside Hospital with Chief Clifford as Santa, and the junkies take hostages.

McCloud is framed for the murder of a drug-dealing hack, and exposes the ring.

A peer of the realm, who's a photographer as well as a cat burglar, comes to America and, in flagrante delicto at a Long Island costume party, witnesses a killing at the hands of Irish bombers, all of which sends McCloud to Blighty, where the target remains to be found.
