Laserblast

Billy (Kim Milford) has the same problems that many teens have to endure. His mother is inattentive, local cops target him for speeding tickets, his girlfriend's grandfather hates him, and teenaged bullies make fun of his van. Billy finds the keys to his emancipation in the desert, when he stumbles across a laser gun left behind by a pair of aliens. As he exacts revenge upon his unsuspecting tormentors, he becomes overwhelmed by the power of the gun and turns into a crazed, green-faced monster.
