Veteran Chicago detective Jim Brannigan (John Wayne, The Searchers) is dispatched to London to bring back notorious gangster Ben Larkin (John Vernon, Dirty Harry), and is assured that the whole operation will run smoothly. However, when things don't go to plan, Brannigan finds himself in the crosshairs of Larkin's thugs. Reluctantly teaming up with by-the-book Commander Swann of Scotland Yard (Richard Attenborough, The Great Escape), but determined to recapture Larkin no matter what, Brannigan tears through London, leaving a trail of destruction in his wake. Boasting incredible stunts, powerful punch-ups, dry dialogue and panoramic views of 1970s London shot by cinematographer Gerry Fisher (The Go-Between, Highlander), as well as a superb supporting cast including Judy Geeson and Mel Ferrer, Brannigan still stands tall as an explosive, action-packed, highly entertaining and peculiarly British excursion for the legendary John Wayne.
