Gravedigger Jones and Coffin Ed Johnson are two black cops with a reputation for breaking the odd head. Both are annoyed at the success of the Reverend Deke O'Mailey who is selling trips back to Africa to the poor on the installment plan. When his truck is hijacked and a bale of cotton stuffed with money is lost in the chase, Harlem is turned upside down by Gravedigger and Coffin Ed, the Reverend, and the hijackers. Much of the humor is urban black, which was unusual in 1970. Gravedigger Jones and Coffin Ed Johnson are two black cops with a reputation for breaking the odd head.
