The Swamp Thing, een geheimzinnig monster uit het moeras, is terug en bindt de strijd aan met de getikte professor Arcane, die in zijn moeras een laboratorium heeft gebouwd waarin hij gruwelijke genetische experimenten uitvoert.
Nee, helaas is The Return of Swamp Thing nog niet beschikbaar op Netflix in Nederland.
