In the fifth episode of "Grimm Variations" titled "The Bremen Town Musicians," the story is set in an altered European city of Bremen, now depicted as a Western landscape. The episode begins with Charlotte discussing a trivial conflict—where a dog chases a cat—with her brothers, searching for parallels between real life and the resolutions in fairy tales.

The story revolves around a former sheriff named Mad Dog, known for her tough stance against criminal gangs. After exposing the corrupt ties between sheriffs and gangs, she is stripped of her position. She then befriends two other outcasts: Donkey, who stands out for his immense strength, and Cat, a former escort who has always resisted oppression.

On their way to Bremen, the trio encounters a young girl enslaved by a gang after her parents refused to pay a ransom. Though she despises the gang, she serves as their lookout to survive. She warns the trio about the gang at a local saloon.

Ignoring the warning, the trio enters the saloon in search of food but finds none. Inside, they witness the gang causing trouble and attacking patrons, including Cat. To defend her, Donkey knocks out one of the assailants. After a confrontation where Mad Dog kills a gang member in self-defense, the gang retreats to plan their revenge.

Mad Dog assumes a protective role toward the girl, expressing her desire to foster a sense of community. When the gang returns for vengeance, a decisive confrontation ensues, culminating in a duel between Mad Dog and the gang leader, which Mad Dog wins.

Afterward, Mad Dog, her new allies, and the girl move into the saloon, forming a community where everyone finds their place. The episode ends with a sense of new beginnings for the gathered group.
