Jennifer Tilly is the mistress of a gangster (Joe Pantoliano). She meets Gina Gershon and they rip off Joe who is holding 2 million dollars of mob money. They make him think a rival ripped him off which causes Joe to kill a couple of gangsters.
He finds out the girls did it and he almost kills them but they turn the tables and kill him.
Jennifer convinces the mob that Joe skipped with the money and she and Gina go live happily ever after.
