Kelly Lynch and Naomi Watts play femmes fatales in the thriller Persons Unknown (1996). Kelly pretends to collide with a rollerblading cop, played by Joe Mantegna. She has a one-night stand with him to get security codes she and Naomi need for a heist. But that’s only the beginning of the two-timing in this arousing action flick. Though Naomi doesn’t get skinful here, Kelly lets her Lynch pins out for a scene that will make viewers see double.
