Wes Craven wrote and directed this adaptation of the DC Comics superhero, once a scientist trying to help humanity, who turns superhuman when he is doused with his own experimental formula to use plants to help humans while in the nearby Louisiana swamp.  Adrienne Barbeau stars as the government agent sent to oversee the lab, with Ray Wise playing the scientist side, and Dick Durock as the hulking alter-ego, Swamp Thing.  Louis Jourdan is the bad guy out to get the formula to use for his own nefarious purposes.

Note: I neglected to mention that next week's show will be on the follow-up, RETURN OF SWAMP THING (1989)
