Programmer's Pick

Only in 1970s London could a jewel thief’s greatest weapon be his bedroom prowess, not his criminal finesse. Martin Campbell delivers a caper where the real cat-and-mouse is played between Grant Henry and his all-too-willing targets. Raunchy, cheeky, and never shy about its nudity, this is British sex comedy in full, unbuttoned swing.

Overview

Grant Henry is a struggling writer of sensational paperbacks who leads a double life as a less-than-stealthy jewel thief. Despite being caught mid-heist by wealthy women, he consistently manages to charm his way out of trouble—often seducing his would-be victims, who then protect his identity and even seem eager for repeat visits. His escapades make him a minor celebrity among London's upper crust, with hopeful socialites leaving their valuables out in anticipation of a nocturnal rendezvous. Meanwhile, a determined police inspector and an insurance investigator trained in kung fu are hot on his trail, concocting an elaborate trap amid the farcical chaos. The film revels in bawdy humor, playful seductions, and the blurred lines between crime and pleasure.
