Laserblast is a 1978 science fiction film directed by Michael Rae.
A green-skinned man wanders through the desert with a laser cannon attached to his arm. A spaceship lands and two aliens emerge, one of whom shoots the man, which disintegrates his body. The aliens depart on their spaceship, leaving behind the laser cannon and a metallic pendant the man was wearing.
Teenager Billy Duncan wakes up and learns his single mother is leaving for a vacation without him. He goes to visit his girlfriend Kathy, but her deranged grandfather Colonel Farley makes him leave before he can see her. As Billy drives around town, he is harassed by bullies Chuck Boran and Froggy, and by two police deputies who give him a speeding ticket.
Billy wanders into the desert and discovers the laser cannon and pendant. He starts playing with the cannon, pretending to shoot things, then realizes he can fire the weapon while wearing the pendant. Meanwhile, on the alien spacecraft, the two aliens converse with their leader who shows them footage of Billy using the cannon, prompting the aliens to turn their ship around to head back to Earth.
Later that night, Billy and Kathy attend a party where Chuck and Froggy attempt to rape Kathy. When Billy discovers them, a fight breaks out. Later that night, Billy uses the laser cannon to make Chuck's car explode, and Chuck and Froggy barely escape the explosion. Government official Tony Craig arrives to investigate both the explosion and the desert where Billy found the cannon. Tony informs the local sheriff that the town must be sealed off.
Feeling sick due to an unusual growth on his body, Billy visits Dr. Mellon, who surgically removes a metallic disc from Billy's chest. Mellon calls the police laboratory technician Mike London to arrange for the disc to be investigated. That night, Billy (whose skin has turned green) opens fire on Mellon's car, killing him in an explosion. The next day, Tony investigates the wreckage and recovers unusual material, which he brings to Mike London, who concludes it is of alien origins and cannot be destroyed. That night, Billy goes to a gas station and kills the two deputies that had bullied him.
The next day, Kathy puts the pendant on Billy's chest while they are laying together outside. Billy immediately wakes up with green skin and deformed teeth and attacks Kathy. Billy goes on a rampage, shooting random objects with the laser cannon. Law enforcement officials shoot at Billy from an aircraft, but Billy destroys the aircraft with the cannon. He later kills Chuck and Froggy by blowing up their new car.
While Tony questions Colonel Farley and Kathy about Billy, the two aliens land on Earth and begin searching for Billy. After killing a man and stealing his van, Billy travels into a city where he randomly fires at his surroundings. Kathy and Tony arrive in the city and locate Billy, as the aliens spot Billy from atop a building and shoot him, killing Billy and destroying the laser cannon. The aliens depart in their spacecraft and Kathy cries over Billy's corpse.
