In a bleak future, the inseparable Batman and Robin live in a remote trailer. As punk-rock reenactors, they realize that planet Earth has become too small for their perfection, genius and power, and decide to find their place in the galaxies.

Having spent years on the road trying to escape the ghosts of his past, Roben despairs when a disembodied presence invades his electronic devices: it is Batma, his former partner. As they discuss the possibilities of a relationship mediated by the cloud, Roben will have to confront his origins, which he has been despised for being just a supporting character - and discover if there is anything left beyond Batma's desire for domination.
