Mutated by his own secret formula, Dr. Alec Holland becomes Swamp Thing; a half-human, half-plant superhero who will stop at nothing to rescue government agent Alice Cable and defeat his evil arch nemesis...Even if it costs him his life.

The Swamp Thing returns to battle the evil Dr. Arcane, who has a new science lab full of creatures transformed by genetic mutation, and chooses Heather Locklear as his new object of affection.
