When an attempt is made on the lives of Canadian boy band, Spaceships Around Saturn, during their USA tour, the guys have to go into hiding ASAP. The Branson sisters are preparing for a summer of beach vacations, pool parties, and festivals.

The only problem? In the midst of the crisis and media frenzy, their secret-service-agent dad volunteered to hide the guys...in their house.

Six-year-old Emery is as ecstatic as any self-proclaimed Saturnite would be, but teens Chloe and Aralie watch their summer plans crash and burn like a falling star. The SAS guys aren't happy with the situation, either. Bad boy Jules picks fights with Aralie about everything from his Twitter followers to his laundry, and heart-throb Benji can't escape Emery's fangirlisms for more than three minutes.

But after the super-cute Milo kisses Chloe during a game of hide-and-seek, she finally understands what Emery means when she talks about SAS being "out of this world." If this is what Saturn feels like, Chloe doesn't want to come back to Earth.
