Victorian gothic melodrama based on the novel by Sheridan Le Fanu from a screenplay adapted by Aldwych farceur Ben Travers. This creepy chiller is saved from the doldrums by Robert Krasker's atmospheric cinematography, and fine performances from the ensemble cast. The BBC later filmed the story for television in 1987. In 1845, 17-year-old Caroline (Jean Simmons) is nursing her dying father. He has enough faith in the reform of his reprobate brother, Silas (Derrick de Marney), suspected but in the clear of murder, to place her under his wing after his death. The hitherto naive heroine soon learns that scheming Uncle Silas is planning to kill her in order to get his hands on the family fortune, aided by the equally corrupt governess Madame de la Rougierre.
