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.

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.
