Bad Taste (1987)

The film opens with a peaceful morning in the remote town of Kaihoro, where the residents go about their daily routines. However, something strange is happening as three men in black suits observe the town from a nearby hilltop.

Derek, an alien exterminator, receives a phone call from "Mr. Assistance" and is briefed about an expected alien invasion in Kaihoro. Derek assembles his team, including Barry, Frank, and Ozzy, and they head to the town to investigate. Meanwhile, Giles, an alien operative disguised as the local doctor, begins luring the townspeople to be processed by the fast-food chain "Crumbs Crunchy Delights." The townspeople vanish mysteriously, and their homes are increasingly inhabited by dismembered sheep carcasses.

Derek and his team arrive in Kaihoro and split up to search for clues. They encounter numerous bizarre events, including finding sheep brains in a field and witnessing a talking sheep named "Sheep (Bob) " before it is killed by an alien in disguise. The team stumbles upon an alien spaceship hidden underground. They explore inside and discover its purpose is to harvest human flesh for intergalactic fast food. They also find a couple of alien foot soldiers, whom they effortlessly kill.

Giles discovers Derek's presence and takes him captive. However, Derek escapes and battles Giles, detonating an explosive that destroys Giles' face. The team regroups and concocts a plan to infiltrate the aliens' headquarters. An alien sniper shoots Barry, blowing a hole through his head. The team comes up with a plan to use Barry's brain to control his body, allowing them to enter the alien base undetected.

Disguised as aliens, the team infiltrates the headquarters while the fast-food chain prepares to launch a full-scale attack on Earth. They take out several aliens in the process and locate their captured friends, who are imprisoned and being prepared for processing.

A massive battle erupts where the team fights against an army of aliens, using a variety of unconventional weapons including chainsaws and rocket launchers. As the battle intensifies, Frank is decapitated and Ozzy is shot through the chest.

Derek faces off against Lord Crumb, the leader of the alien invasion. After a grueling fight, Derek tosses Lord Crumb off a cliff and detonates a bomb, destroying him alongside the alien base. Derek manages to save Barry, who has been controlled by his own brain, by inserting it back into his head.

With the battle won, the surviving team members gather together, injured but victorious. They share a few laughs before realizing that Ozzy is still alive, but his chest wound has transformed him into an alien-human hybrid.

The film ends with a surreal twist as a spaceship lands, and a group of alien exterminators identical to Derek's team emerge. The newcomers declare that they are there to clean up the mess created by the previous team.
