When Joe and Fran are brought together to prepare for the inaugural launch of this revolutionary rocket, there are immediate sparks, but neither is particularly adept at romance. Life becomes more complicated when three aliens—tiny, unruly and adorable—take refuge in Joe’s home. Dunk, Welly and Shirm are on the interplanetary run from a zealous-yet-inept officer of the law named Zandro. The aliens determine that Fran’s rocket could provide their means of getting back home to safety.
