After Chief Superintendent James Hooper was able to arrest the legendary Gentlemen mail robbery gang, he is only missing the head of the gang. But the extremely shrewd Michael Richy Richardson plays a cat-and-mouse game with the man from Scotland Yard, who has been chasing the gentleman gangster across the globe for years now. Richy changes identities like he changes suits, slipping Hooper through the net again and again. He is slowly running out of time, as his retirement is imminent. In well-deserved retirement, Hooper's final hunt begins anew, as the dogged ex-chief inspector is unwilling to let the super gangster escape.
