Mr. Chen (1970)

Two old friends, one severely down on his luck, reunite to attempt a get-rich quick scheme that goes, predictably awry. Hard-luck Paul, recently out of a job and rudely dumped by his girlfriend, has to sell his car in order to pay his rent. Lying around in a depressed fog, he is contacted out of the blue by an old friend, Freddie, a mysterious man ineptly obsessed with all things Asian. He has come to town to conduct some kind of quasi-legal business transaction he is convinced will leave him wealthy. As Paul learns more about the scheme, he becomes inexorably involved until he has to put everything on the line.
