Nightbeast

A small alien spaceship is cruising around the solar system. When it reaches the vicinity of Earth, it is struck by an asteroid and crashes at night in the small town of Perry Hall. Some hunters hear the impact and alert County Sheriff Cinder. When they go investigating on their own, however, the pilot emerges and kills them with a disintegrator ray. The beast also attacks a couple in their home, and a family out for a drive.

Cinder confronts the beast with his men and some armed residents including a man named Jamie. However, the beast appears invulnerable to bullets and they lose many men to the disintegrator. The next morning, they enlist the help of an expert marksman who shoots off the disintegrator, disarming the beast. However, the marksman's son and another officer perish during the shootout.

The police department begin evacuating the town. However, they are unable to convince mayor Bert Wicker to cancel his party for governor Embry. Meanwhile, a delinquent named Drago abuses his girlfriend, who has been sleeping with Jamie. The police then arrive to give her the evacuation order, and after they leave, Drago returns and strangles the girl. When Cinder's police find out that Wicker's party is in progress, Jamie bluffs that poison gas is escaping from a nearby mine and the partygoers flee in panic. Wicker and his secretary Mary Jane, dispirited by this turn of events, stay home and begin drinking heavily.

At the office of doctor Steven Price, the beast appears and kills a few men. Price and nurse Ruth hide in the basement, and devise a trap to electrocute the beast with some frayed electrical cord. It works, and the beast flees the building. The body of Drago's girl gets discovered and taken to Price; Jamie, suspecting Drago, goes out on his dirt bike and beats him. Soon after, Cinder and his deputy Lisa discover a mutilated corpse, and the beast shows up. Lisa and Cinder make their escape, and the sheriff injures his leg in the process. Lisa takes him to her house to heal, and they have sex.

Meanwhile, Wicker and Mary Jane have gotten very drunk. Price is sent to watch over them until they can be evacuated. However, the beast gets past Price and kills Mary Jane in the basement. Her screams wake Wicker, and the beast rips his head off when he investigates. Cinder arrives afterwards, and Jamie suggests electrocuting the beast with a high-voltage coil from the local power plant. Price, thinking back to his success with the electrical trap, supports this course of action, and the sheriff drives out to the power plant with his men. There, Drago assaults Ruth and Cinder, but is stopped when Jamie shoots him with a shotgun.

Cinder and his crew return to Wicker's house and begin setting up their trap, laying metal wire between the trees and connecting it to the coil, which will discharge when they throw the circuit breakers. The beast takes them by surprise, and Jamie must hold onto the wire to keep it inside the trap. They throw the breakers, and the surge makes the beast explode, and takes Jamie with it as well. The camera pans up to the stars overhead and the film ends.
