Blaxploitation movie from 1974. Starred Pam Grier as the title character. It is notable for having a strong FEMALE protagonist fighting AGAINST pimps and dealers — in this case evil white people. Most other blaxploitation movies had a male pimp/dealer as the protagonist, like in Superfly.
In Foxy Brown, Pam Grier witnesses her lover's murder, disowns her brother, frees young black woman from lesbians and white pimps, beats the crap out of said lesbians and white pimps, gets kidnapped and raped by white slavers before blinding them with a wire hanger and blowing up their heroin lab while the crackers are still inside, dismantles a criminal empire run by a white lady named Catherine and cuts off a honky's wee wee.
