Nikola Tesla has been lost in the multiverse, using his device to travel through multiple versions of earth, trying to find his way home. Unfortunately, he has inadvertently built up a huge debt to the agency that manages inter-dimensional travel. After he disappears Harriet is recruited by the Multiverse Unification Agency to help Nikola in a confusing and sketchy sales job between worlds.

When Harriet’s boyfriend Alonso is drawn into the agency, Harriet must keep him from being vaporized, while an interdimensional death cult tries to vaporize everyone and everything in the 628.608 universes.
