John Wayne stars as an aging ornery cop sent from the rough-and-tumble beat of Chicago to merry ol' England to retrieve a fugitive racketeer. Richard Attenborough co-stars.

John Wayne cast aside his usual Western gear to portray a tough Irish-American detective on assignment in London to catch a crook who fled the United States to avoid extradition. Wayne's partner in criminal hunting is a British Inspector (Richard Attenborough) with a very different personal style. After a rough bit, they become partners and cooperate in a rousing batch of car chases, false and good leads, booby traps, etc., before they trap their man. Detective Wayne finds time for some heavy flirting with constable Judy Geeson (TO SIR, WITH LOVE), who would prefer that Wayne's flirting was considerably less heavy. Screenplay co-written by Christopher Trumbo (son of Dalton Trumbo).

This offbeat John Wayne vehicle casts the Duke as Detective Jim Brannigan, an Irish-American detective at large in London. After the requisite culture-clash routines, it's down to business as Brannigan teams with Scotland Yard official Commander Swann (Richard Attenborough) to corral a crook who has absconded to England to avoid extradition. Judy Geeson co-stars as Jennifer Thatcher, a cute lady constable who spends most over her time fending off Brannigan's inbred chauvinism. Brannigan was co-written by Christopher Trumbo, the son of former blacklistee Dalton Trumbo. ~ Hal Erickson, All Movie Guide.
