Jack Davies, an art dealer from London, does a deal with his friend, Michael Clare, son of a gifted artist, Victor Clare. Michael steals some of his father's works and Jack sells them at his gallery, splitting the profit with Michael. Both men realize that Victor works are worth a fortune. Unfortunately, Victor is a recluse, and lives in isolation above an abandoned tin mine in Cornwall. It would be impossible to smuggle out any more of his paintings without being noticed. You really must watch this classic horror to see the surprise ending. This is vintage horror at its best!
