Famed barber Sweeney Todd draws the attention of the old gods struggling to find a place in the mythos of a changing world. Zeus visits in the guise of a normal man and then becomes engaged when he realizes he's been fed human flesh. To punish him for this slight, he curses him with Lycaon's own: Todd now becomes a wolfy beast to further terrorize the streets of London.

Wait, no, Lovett is the one preparing and serving the food. She becomes the werewolf. Hijinks ensue.
