Leprechaun: In the Hood, is the fourth movie in the Leprechaun series.
An unsuccessful rap artists Postmaster P., Stray Bullet and Butch accidentally free the Leprechaun that was imprisoned by record producer Mac Daddy O'Nassas 20 years earlier. The Leprechaun hunts the friends in order to recover his magic flute, which places listeners of its tune in an euphoric trance. After killing some people, such as a Reverend, some DJ artists and a hot girl, The Leprechaun reaches the three friends at Postmaster P.'s home. When the rap artists and the Leprechaun engage in a fight, the Leprechaun kills Stray Bullet by making him shoot himself in the mouth with his own pistol while Postmaster P. and Butch stare in horror. Butch visits Postmaster P at his grandma's house and convinces him to use a joint laced with clovers to strip the Leprechaun of his powers in order to steal back the flute.
Postmaster P. and Butch then visit the club in which the Leprechaun has taken up residence. In order to gain entry they dress in drag. Postmaster P then disenchants the Zombie Fly Girls by having them smoke one of the joints laced with clovers. The duo then goes upstairs to find the Leprechaun who wants the dragged up Postmaster P to give him a blowjob. Before proceeding any further, the Leprechaun smokes the clover laced joint and passes out. The rap artists take the flute and head downstairs where Mac Daddy shoots Butch, killing him. Postmaster P retaliates by shooting Mac Daddy three times. No longer under the effects of clover, the Leprechaun comes downstairs and uses magic to pin Postmaster P against a girder. Postmaster P then distracts the Leprechaun, allowing the bullet-ridden Mac Daddy to hit the Leprechaun with a wooden chair. Immediately, the Leprechaun uses magic to explode Mac Daddy's torso, but with the last of his strength, Mac Daddy throws the magic amulet in the air.
Cut to a dark stage with much fog and a silhouetted Postmaster P rapping about how he's finally made it. He moves to the forefront where his eyes are hidden behind sunglasses. He removes the sunglasses to show that his irises glow a neon green indicating that he is under the Leprechaun's spell. The camera pans to the front row, in which the Leprechaun sits wearing the same glasses as Postmaster P.
The movie ends with the Leprechaun rapping about being an evil Irish Leprechaun, and at the same time, he took mind control of waitresses, who became Zombie Fly girls again.
