Hydra

Two months after a blood-soaked scientific expedition at an isolated volcanic isle and the emergence of its ancient, long-dormant monster, a group of wealthy thrill-seekers decides to take part in a deadly game. But with four ex-convicts marooned on the same island, the dangerous hunting game soon brings both the hunters and their prey face-to-face with a scaly multi-headed adversary from the depths of Greek mythology. Is there someone, or something, that can stop the serpentine Lernaean Hydra?
