During the tumultuous days of World War Two, amidst the frenzy of technological innovation, the Nazi regime concocted a chilling weapon unlike any other - giant mutant ants. In a daring operation, a Nazi submarine covertly released a mating pair of these monstrous insects on Swans Island, Maine.

With a voracious appetite and unchecked reproduction, the ants swiftly established a thriving colony, posing an unprecedented threat to the local residents and the nearby Coast Guard detachment.

The once peaceful island is transformed into a battleground as the human inhabitants valiantly fight for survival against the relentless onslaught of the giant ants, struggling to quell their insatiable hunger and prevent the spread of this Nazi-engineered terror.
