An expedition of United Nations scientists from different countries travel to Bear Island, between Svalbard and northern Norway, to study climate change. However, several of them are equally interested in the former German U-boat base located on the island, including American marine biologist Frank Lansing as his father was a U-boat commander who died there. Expedition leader Gerran places several parts of the island off-limits, including the U-boat base. Directed by Don Sharp and starred Donald Sutherland, Vanessa Redgrave, Richard Widmark, Christopher Lee and Lloyd Bridges.
