Sometime in the last century, Alex Olsen and Damien Ridge had been best friends. However, they both vied for the affections of a woman named Linda. Linda eventually married Alex and Damien had to endure his heartache in the form of the supportive friend. But his desire for Linda overrode the bonds of friendship and he conspired to eliminate Alex. He sabotaged the equipment in Alex's lab causing an explosion that killed him. Keeping the knowledge hidden from Linda, Damien buried Alex's body in the swamp.
Damien eventually married the widow Olsen and they lived together in an old Victorian plantation house. But Linda never recovered from Alex's death. As months passed, Damien began to suspect that Linda might soon learn the truth, so he prepared to kill her. But Alex had been resurrected as a swamp thing and broke into the house and killed Damien. Linda fled from the creature in horror, never realizing that the beast who saved her was her beloved Alex.
