Blackout (aka Murder by Proxy)

Down-and-out Canadian Dane Clark is soused in a London club the night he's approached by a beautiful stranger (Belinda Lee) offering him 500 pounds to marry her. The too-good-to-be-true offer turns sour when Lee goes missing and her wealthy father is found murdered. With only hazy memories of that unusual night, Clark doesn t know himself if he is the killer.
