Edward Lionheart (Vincent Price), a demented Shakespearean actor, adds murder to his repertoire when he takes gruesome revenge on the eight critics who slighted him. He knows he deserved that major award for his fine acting, but once again, the critics denied him and chose some other, inferior performer. So now he's going to make them pay. All it takes is a faked suicide so they believe him dead, and a few murder scenes taken directly from Shakespeare's plays.... Then, one by one, the eight judges will experience Lionheart's version of poetic justice. His loyal--and equally demented--daughter (Diana Rigg) abets him in his grisly plan.
