Mortimer T. Flightdeck, Ratonaut and Future YouTube Sensation, has big plans for ratkind. A spot on the International Space Station (ISS) has opened up, and Mortimer, is not about to miss his chance to become an intergalactic space rat. And that's just the first step in his master plan to prove that rats are much better suited than humans for a future mission to Mars. He packs his camera and prepares to take to the internet with his evidence of rat superiority. But when Mortimer's schemes go awry, he is forced to face new truths about dreams, friendship, and choosing the right thing to do. Maybe not everything is a rat race.
