It is an island that doesn't appear on any maps. A secret place, where classified experiments have been carried out. Experiments that have gone terribly wrong... Four crack special forces units are dropped in. One of them is a team of Marines, led by Captain Shane Schofield, call-sign: SCARECROW. Nothing can prepare Schofield's team for what they find there. You could say they've just entered hell. But that would be wrong. This is much, much worse.
