Plot
In 1914, a young Englishman travels to a remote island in the South Atlantic to work for one year as a weather observer. It soon becomes obvious that the man he is replacing is missing. The only other inhabitant of the island is the caretaker of the crudely fortified lighthouse, Gruner. Gruner says the previous weather observer cannot return with the ship as he has died from typhus, possibly swimming in the sea, and there is no body.
The unnamed man explores the island, seeing strange rock circles on the beach. When he returns to the cabin he finds the diary of the previous meteorologist with drawings of local wildlife including strange creatures from the sea. Soon after reading this he is beset at night by the creatures trying to gain entry to his cabin. The next day he calls to Gruner to let him into the lighthouse, but to no avail. That night when the creatures come again he lights a fire against them, only to burn down most of his cabin.
The next day as the man explores the island, he discovers a female sea creature. He raises his gun, but Gruner arrives and prevents him from shooting her and shows that she is "tame." Gruner gives the man the name "Friend" and he explains that like a dog she will not leave her master (Gruner) no matter how cruel he is.
