A holy warrior nun sets out to liberate the poor, hapless girls from the clutches of the vile grubmen. Rigorously trained in the arts of chastity and restraint, as well as in the blade, she feels confident, despite the dangers. Finding her way into the breeding facility, she soon finds herself trapped in a cage with a waiting Grubman, already emitting pheromones to seduce and break her defenses. For a moment, she almost falls for it, but is able to fight off the creature's wily ways. Soon, however, she meets her match: an evolved Grubman mutant with far more potent powers of persuasion. Soon she too falls for the Grubman challenge and succumbs to the desires to breed with the monsters.
