The film follows the story of Sir Robert Cargrave (played by Ronald Lewis), a British doctor who receives a letter from his former lover, Maude Sardonicus (played by Audrey Dalton), urging him to come to her aid in the remote village of Gorslava, in central Europe.

When Sir Robert arrives in Gorslava, he discovers that Maude has married the wealthy and eccentric Baron Sardonicus (played by Guy Rolfe). The Baron is known for his cruel and tyrannical behavior, and the villagers live in fear of him.

Sir Robert learns that Maude is being held captive by the Baron, who reveals that Maude's face has been frozen into a grotesque, permanent grin due to a condition known as "sardonicus." The Baron demands that Sir Robert use his medical skills to cure Maude's condition, threatening her with further torture if he refuses.
