A Fleet Street barber named Sweeney Todd (Tod Slaughter) builds up a fortune by enticing sailors into his shop. No sooner are they in his chair than he slits their throats, robs them, and drops them through a trapdoor into a vault below. To dispose of the bodies, his girlfriend Mrs. Lovatt (Stella Rho) runs a meat-pie shop next door. All goes well until Sweeney flies high and tries to win Johanna (Eve Lister), daughter of a prosperous ship owner. This excites the jealousy of Mrs. Lovatt and creates problems from Sweeney Todd.
