BAD TASTE

After the town of Kaihoro's entire population disappear, the Astro Investigation and Defence Service (AIDS) sends their agents Derek, Frank, Ozzy, and Barry to investigate. They find the town overrun by man-eating aliens disguised as humans in blue shirts. Barry kills one of the aliens and is attacked by others. After Derek notifies Frank and Ozzy, he begins torturing Robert, an alien they caught earlier. Robert's screaming attracts a number of aliens. Derek kills the would-be rescuers, but he is attacked by Robert and falls off a cliff ledge, to his presumed death.

Meanwhile, charity collector Giles passes through Kaihoro. He escapes Robert's attack and comes to nearby house for help, only to get captured by another alien. Giles later wakes up in a tub of water filled with vegetables and is told he is about to be cooked and eaten. Derek wakes up in a seagull's nest with a hole in his head, so he uses a hat to keep his brains from leaking out.

That night, Frank, Ozzy, and Barry infiltrate the aliens' house and find a room filled with bloody cardboard boxes, likely containing the corpses of former Kaihoro residents. They kill an alien, and Frank wears its shirt to infiltrate their meeting. He learns that the victims have been harvested for food and hears of their recent hostage, Giles. The alien later dines on Robert's vomit, and the disguised (and disgusted) Frank has to follow suit. He escapes and tells the others of the plan. They save Giles as the aliens sleep.

At sunrise, they try to leave but are attacked by the aliens, and a gunfight ensues. Derek emerges and joins the fight, using his belt as a headband when the hat is shot off. He grabs a chainsaw from the boot of his car and heads for the aliens' house. As the group leaves with Giles, the alien leader (Lord Crumb) and his followers morph into their true form and follow. Ozzy uses a rocket launcher to explode Frank's car, which has been overrun by aliens.

Frank and Ozzy hunt for Lord Crumb and kill many aliens along the way. Meanwhile, Derek kills an alien with his chainsaw and replaces the missing parts of his brain with its brain. An alien prepares to shoot Frank and Ozzy, but it is beheaded by Derek. Frank and Ozzy are shocked to see him alive, and see he has lost his mind.

After they escape the house, Lord Crumb shoots Ozzy in the leg and Frank fires his rocket launcher at the leader, but misses. Lord Crumb knocks out Derek and the house transforms into a giant spaceship and blasts off into space.

On board, Derek looks out the window to see Earth. He ambushes Crumb and kills the alien with his chainsaw. He proclaims war on the alien, then puts on the alien leader's skin and laughs maniacally as he rockets towards the alien planet.

Back on Earth, the survivors drive away in Derek's car.

Derek and his team battle the aliens, with Derek ultimately boarding the alien spaceship, killing the alien leader, and setting course for the alien home planet while the others escape.

Derek’s grotesque transformation and final confrontation signal a gleefully anarchic sendoff, with the protagonist taking the fight to the aliens rather than restoring the status quo on Earth. The ending cements the film’s commitment to outrageous escalation and delivers on its promise of splatter-soaked action, leaving Derek—now sporting the alien leader’s skin—hurtling towards new cosmic chaos.
