Since Francine's babysitter is somewhere else and Commander Nebulon is leaving the house for the weekend, Lloyd is forced to take care of Francine for the weekend, but it turns into a disaster since Francine is breaking stuff and will blame Lloyd for the stuff she has broken. Lloyd then takes Rosie (Francine's favorite toy doll) and straps onto a rocket ship in order to force Francine to behave.
