Financial troubles force a recent divorcee and her teenage sons Mike and Sam to settle down with her father in the California town of Santa Carla. At first, Sam laughs off rumours he hears about vampires who inhabit the small town. But after Mike meets a beautiful girl at the local amusement park, he begins to exhibit the classic signs of vampirism. Fearing for his own safety, Sam recruits two young vampire hunters to save his brother by finding and destroying the head vampire.
