Thurgood Jenkins (Dave Chappelle) and his friends Brian (Jim Breuer) and Scarface (Guillermo Diaz) are forced into selling marijuana stolen from the lab where Thurgood works as a "master of the custodial arts" (janitor) in order to bail their friend Kenny (Harland Williams) out of jail, after he accidentally kills Buttercup, a diabetic police horse, by feeding it junk food. Their business, named Mr. Nice Guy in honour of their good-natured incarcerated friend, becomes immensely popular, even attracting famous clientele. Thurgood's personal life is ruined once his adamantly anti-drug girlfriend, ironically named Mary Jane Potman (Rachel True), discovers that he works for Mr. Nice Guy. Soon, all of their lives are in danger once Samson Simpson, a local drug lord, learns that Mr. Nice Guy is costing him business, including his former client rapper Sir Smoke-a-Lot. He threatens to kill them if they do not pay him 20 grand every week. Brian buys a pouch that is supposed to contain the ashes of Jerry Garcia with some of the money they are making, and Scarface buys a rottweiler named Killer.

Thurgood tells police about a future meeting he has with Samson Simpson after they arrest him for stealing marijuana from the laboratory. The police agree to drop the charges if Thurgood wears a wire, that way they can get the proof they need to arrest the drug lord. Before the guys go into Samson's home they smoke a joint in the police van. The cops get high from the second hand smoke. The cops tell them to say abracadabra when they have purchased the drugs. During the interview, Samson discovers that Thurgood is wearing a wire and is about to kill them. They scream abracadabra into the wire to try to get the cops to save them. But the cops are high from second-hand smoke and busy mocking a letter Thurgood wrote to Mary Jane. A fight breaks out with Samson and his army of women. Brian throws the pouch he bought earlier on the ground. The ghost of Jerry Garcia emerges and hits Samson with a guitar, knocking him out. The police then rush in and recover all of the drugs, and arrest Samson after he wakes up. Thurgood, Brian, and Scarface's deal with the police works to get Kenny a pardon from jail. Thurgood gives up smoking and is able to win back Mary Jane whose dad is a marijuana dealer.
