For a group of ship wrecked people, it's a dream come true to find themselves on the Isle of Legends, a ready to open resort with a zoo of animals genetically altered to resemble mythical beasts. While some of them indulge in the luxuries of the resort, others are skeptical of the excess around them and of the dangers of tampering with nature to make new life. These worries start to come true when a teen named Sally finds a half human, half cat hybrid. After naming him Johnny, she starts teaching him about the civilized world while learning about his race, causing her to question what makes us truly human and about our place in nature. As she befriends him, she starts to suspect that the resort's owner, Dr. Peccazillo, has lied about his zoo animals, making her wonder what else he's keeping hidden from the group. Ultimately, Sally's concerns about the zoo become true when the animals escape their pens and go on a rampage, destroying the resort and attacking everyone they encounter. Will the group of castaways survive as the zoo's dark secrets start to surface and put their very lives in danger? Or will the power of nature be able to save them from what science has created?
