On his journey to find Swamp Thing, John Constantine discovers the motive behind the plant elemental’s new brutal and savage behavior: With Alec Holland’s resurrection (in the pages of BRIGHTEST DAY), Swamp Thing finds itself without a human consciousness, and The Green within becomes an uncontrollable force of evil. But as John continues to search for Swamp Thing to get the answers he needs, he realizes that his prey has taken on the role of the predator and is seeking him out as well. Why? The Green needs a new human, and John just happens to fit the bill to play host within its dark psyche.
In order to prevent himself from being consumed, John will need to travel to Metropolis and enlist the help of Superman. But will even the Man of Steel be able to help against the magic forces at work here?
