Demi Moore in Striptease (1996)

Erin Grant loses care and custody of her daughter when she’s divorced from her husband Darrell, a small-time thief. Struggling for money, she is a dancer at a nightclub, where one night Congressman Dilbeck (in disguise) attacks another member of the audience. A spectator, who recognizes Dilbeck and is fond of Erin, offers to get back her daughter by blackmailing Dilbeck. Things do not work out as planned, though.
