Martin's attempts at filming his own horror movie are interrupted when a giant ant emerges from the screen of the local Drive-In which is showing an old sci-fi movie about giant insects. Martin and Diana soon discover a 500 year curse is bringing imaginary monsters to life and since Java was playing the creature in Martin's movie he's been transformed into a real radioactive swamp zombie. To make matters worse if the monsters aren't all defeated by sunrise they'll become indestructible and Torrington will never be rid of them.
