Mutilations(1986)

Mutilations is a sci-fi horror film that follows a high school science teacher who leads his class on a field trip to investigate a reported UFO sighting. When they arrive at a remote farmhouse, they discover the sighting was real—a crashed flying saucer has landed on the property. What begins as an exciting discovery quickly turns into a nightmare when an alien predator emerges from the wreckage, hungry for human flesh. Trapped with nowhere to escape, the students are hunted down one by one in a desperate fight for survival. As the creature picks off the group systematically, the teacher must find a way to protect his remaining students and stop the extraterrestrial threat before it's too late.
