When Terry McGinnis and his friends try to go on a quiet camping trip to a river island near Gotham, they enter a lost world of genetically altered creatures kept prisoner there for the amusement of the world's most dangerous gamehunter: Stalker! It's up to Batman to keep himself and his friends alive, if he can outrun, outwit and outfight the half-dinosaur/half-jungle animals populating the island!
