Mistaken Identity is a Hong Kong Crime-Comedy directed by Tsui Siu-Ming and starring Richard Ng.

Tim Wong's marriage is pretty shitty. His career-driven wife, Diana, is more interested in her TV script writing job than her husband. Tim suddenly finds himself involved in a torrid affair with an old girlfriend, sexy Siu-Man. Unfortunately for Tim, she has a very jealous boyfriend who is secretly a hit-man for the triad.

A couple camping in the woods is attacked by a trio of thugs and the wife is beaten and raped. A few months after the assault, she is hunting down the three (who happen to be diamond smugglers) by posing as a dealer looking to sell some stolen merchandise. Meanwhile, her Interpol agent husband is doing some tracking of his own in the hopes of bringing them to justice. As they make their plans, a group of ninjas is watching from afar, waiting to make their move. A Hong Kong cut and paste edit of the 1985 Korean Film "밤을 벗기는 독장미" (Poisonous Rose Stripping The Night) with new ninja scenes.
