Australian cop Scobie Malone (Rod Taylor) is spurred into action when he has to bring fellow Australian and diplomat Sir James Quentin (Christopher Plummer) back home from London. Sadly, the diplomat is being escorted back to his native land on an old charge of murder -- which puts Quentin's own life in danger. Scobie has his work cut out for him and lays his reputation on the line to bring the commissioner back in one piece.
