The film's story: a group of affluent people aboard a yacht find themselves in harms way after their yacht is damaged during a storm at sea. The yacht runs aground on an island. The survivors of the ship wrecked yacht wade ashore and a short time later discover a rotting, seemingly abandoned derelict ship that is beached close by. An inspection of the derelict, mold covered and dilapidated vessel doesn't reveal much but left over documents on board the abandoned ship suggest some kind of scientific research was being conducted. A night time visit to the derelict vessel by an unknown intruder creates, along with the fog shrouded island and the rising tensions between the group members, an atmosphere of terror and suspense among the human cast of characters.
The group of survivors, when not making tentative forays farther into the island interior, subsist on canned food for a time: after their canned fare runs out they decide to try and find other food sources on the mysterious island. It quickly becomes apparent the island is teeming with mushrooms. Despite being warned by the yacht's captain not to consume them, the other survivors eat the mushrooms anyway, which sets in motion a series of events that may very well kill them all...(no other spoilers)
