Successful barber, Sweeney Todd, has for years been haunted by the loss of his parents at the hands of a cruel judge. One fateful night, his path crosses with local baker, Mrs. Lovett, a woman who too has suffered a devastating miscarriage of justice by the same man and his corrupt associates. Scheming to put a deadly end to the cycle of abuse and exploitation, Todd and Lovett make a pact, leading a macabre charge for revenge against the Victorian upper class, and all who dare stand in their way.
