While living rough on the streets of London's East End, a young man named Dink encounters the mysterious Dee and they begin a relationship. When tenderness gives way to cruelty, they become consumed by darkness.

Sweeney Todd, a barber, and Maggie Lovett, a baker, join forces to commit a series of brutal, gory murders in London with a little help from Tobias Ragg, an employee of Maggie's bakery. They abduct a number of customers from the barber shop and kill them, baking them into meat pies which are sold to the public.
