Graveyards figure prominently in this Spanish horror film. Scotsman Michael Sharrington (Bill Curran) doesn't believe the midwife's story that his wife died in childbirth while he was away. He digs up her grave and finds it empty. Something arouses his suspicion, and he discovers that the other coffins in the graveyard are also empty. His activities have not gone unnoticed by the culprits who abduct him and throw him into the crypt of the local castle, his brother's home. Something beside him is breathing in there, under the ground.
