Duke has arrived in town to bury his brother and decides to reopen his brother's bar. The police expect payoffs to keep the bar open and when Duke refuses to pay, he almost winds up like his brother. But, Duke brings in reinforcements (most notably the beautiful and talented Aretha, played by Pam Grier) to wipe out the corruption until he realizes his friend is double-dealing and he has to wipe him out, too.
Duke Johnson, a tall, handsome northerner, breezes into the degenerate southern municipality of Bucktown to settle his late brother's estate. A small town chock-full of pimps, prostitutes, players and pushers, Bucktown's bad news. But before Duke can sell off his brother's primary holding -- the nightclub Alabama -- he gets involved with redneck police officers running a vicious extortion ring. So Duke calls in a few old friends to help him play hard ball. He and his posse are gonna rid Bucktown of all its stinkin' pigs.
