Silver Bullet (1985)
Whenever the moon is full... it comes back!
A small mountain community is terrorized by a half-man/half-beast of folklore. After an encounter with the murderous werewolf, wheelchair-bound Marty Coslaw becomes saddled with the unfortunate knowledge of the beast's human alter ego. With some help from his sister, his goodhearted alcoholic uncle, and his turbo-charged wheelchair, he sets out to rid the town of the murderous scourge.
