Alien warriors Diana and Apollo, having fled to Earth after their home planet was destroyed, possess a combined power thousands of times stronger than individually, capable of defeating any foe. Targeting their strength, Dr. Darkness, a high-ranking commander of the Death God Army, develops a device that generates alternate dimensions and traps Diana within one. Fighting alone, Diana is unable to equip her powered suit, battling enemy grunts while desperately searching for an escape. Along the way, she's captured by a new monster, Octopus, and taken to the enemy base. There, she's tortured with a small shockwave device and bound tightly with chains. Soon after, she's seized by the leader of the Death God Army, the Evil Death God, who demands she become his wife. Diana fiercely resists, but gradually weakens under the combined effects of icy stimulation and a powerful aphrodisiac that sets her body ablaze.
