Terror Is a Man

A castaway, William Fitzgerald, is rescued by a secretive scientist, Dr. Charles Girard, on an island where the native inhabitants have fled due to superstition. The only remaining people are the castaway, the scientist, his wife, his assistant, a native servant, and her son. However, there may be another person on the island - a panther being surgically transformed into a human by Dr. Girard. But as the creature becomes more human, it begins to pose a threat to the human inhabitants.
