When his henchmen fail to capture Swamp Thing, Dr. Arcane uses his Transducer machine to turn them into mutants to attack Swamp Thing. Two kids, Delbert and J.T. along with a game warden, Tomahawk and Bayou Jack with the help of Arcane's step daughter Abby come to Swamp Thing's rescue.

Dr. Arcane and his Un-Men travel to the Amazon Rainforest in search of “the trees that never die,” and enslaves a local Indian tribe to harvest their sap.

Swamp Thing, Bayou Jack, and Tomahawk help NASA retrieve a nuclear-powered satellite that has crash landed in the swamp. Meanwhile, Arcane desires the satellite for his own advantage.
