In a dark and misty London, a barber named Benjamin Barker is separated from his beloved and wrongfully imprisoned by a corrupt magistrate. Upon escaping from prison, he returns to the city under the name Sweeney Todd, eager to take revenge on those who destroyed his life. Reuniting with his cherished Lucy, who has fallen into the clutches of her oppressor, Todd vows to make his enemy pay for the pain he has inflicted. However, madness and despair consume him as he plunges into a cycle of vengeance.
In his new home, he meets the clever and shrewd Mrs. Lovett, who runs a bakery that has seen little success. Together, they devise a dark plan: Todd will return to the barbering business, but his cuts will become more than just a beauty service. With Mrs. Lovett's help and her meat pie creations, they transform Todd's crimes into an unusual and macabre enterprise that attracts customers.
However, as the shadows of his past and his insatiable thirst for revenge loom over him, Todd finds himself caught between his inner demons and the consequences of his actions. This dark tale intertwines a story of thwarted love, madness, and biting social critique, in an environment where life and death blur in a chilling manner, leaving all who cross his path at the mercy of a cruel and inevitable fate.
