Fieras sin jaula Trilha sonora (1971)

A young girl marries the wealthy father of one of her female friends at college, but she soon finds herself falling in love with another young man. The husband finds out about the two, and comes up with what he believes to be a foolproof plan: he will frame his wife and her lover for his own murder, then have the pair locked in a room in his remote, isolated estate... With his own dead body.
