Oceanic Air flight 815 tore apart in mid-air and crashed on a Pacific island, leaving 48 passengers alive and stranded on a remote island in the South Pacific. The survivors include a diverse group of people from different walks of life -- a doctor, an escaped fugitive, a con man, an Iraqi interrogator, a married Korean couple and a man formerly confined to a wheelchair who is now inexplicably healed. As the castaways attempt to get home, flashbacks (and forwards) illuminate their troubled lives before and after the crash, when the island they find themselves stranded on begins to slowly reveal its mysterious nature. Faith, reason, destiny and free will all clash as the island offers opportunities for both corruption and redemption.. but as to its true purpose? That's the greatest mystery of all.
