A private plane carrying the daughter of a rich businessman crash-lands on the uninhabited island of San Miguel off the coast of Mexico, an island regarded by the locals as cursed. The businessman's Chief of Security, Scott Davis (Mark Kiely) mounts a high-tech mission to rescue the survivors, and in his search to find a guide, comes across Frank Brodie (Ron Perlman), a man who was on the island ten years previously. Davis finds Brodie to be a brooding, reclusive drunk, haunted by his experiences on the island, and Brodie tells Davis that it isn't worth mounting a rescue mission as the survivors will, by now, be dead. Brodie, however, decides to tag along, bringing along a veritable arsenal of weapons and a fatalistic attitude, ridiculing Davis' plans as naive. Accompanying them is Tara Matthews (Roxana Zal), a young woman purporting to be a medic, and Davis' second-in-command, Eddie Mendoza (Guillermo Ríos), a down-to-earth practical man who very quickly realizes Brodie knows what he is doing and is inclined to believe what the man says. Bringing up the rear is Kovacs (Julian Sedgwick), the tech-whiz of the group, complete with thermal-re-con equipment and a high-tech communications system. On landing on the island it soon becomes very clear that they are not alone - something is out there watching them, and the trip rapidly descends into a nightmare.
