Fifteen year-old horror fan Gene Loomis (Simon Fenton) who can't wait for the arrival of filmmaker Lawrence Woolsey (Goodman), who is in town to premiere his latest offering of atomic power gone berserk, "Mant." But the absurd vision of Woolsey's take takes on a sudden urgency as the Cuban missile crisis places the real threat of atomic horror just 90 miles off the coast.
With the help of Gene and his high school friends, along with Woolsey's leading lady, Ruth (Cathy Moriarty), the master showman gives Key West a premier they'll never forget. The screen explodes in "Atomo-Vision," the theatre rocks in spine-tingling "Rumble-Rama," and a local hood threatens to run off with Woolsey's profits. It all seems fitting in this entertaining tale of backyard bomb shelters, missile attack drills and innocence clouded by the threat of nuclear destruction.
