All the protagonists move about in a Tokyo Bar that has an entire wall taken up with a black-and-white reproduction of a photo of Monument Valley. The action starts as Billy the Kid, in full living color, walks out of the photo and gets a job as a waiter.

The plot (as such) revolves around keeping away the brutal mobsters and thugs who dominate the city streets outside of the bar, making the tavern safe for its easily recognized facsimiles of well-known characters.
