David isn"t happy about leaving Florida and his friends to summer with his crazy grandmother in "Middle-of-Nowhere," Washington. Arriving at her Intergalactic Bed & Breakfast, he isn"t surprised by its the-60"s-meets-Star-Wars d cor, but he is surprised by the weird-looking guests. It turns out that each room in the inn is an off-earth portal and his grandma the gate-keeper, allowing aliens to vacation on Earth. Grandma desperately needs David"s help monitoring the visitors, shopping for cartloads of aluminum-foil for dinner, and taking rambunctious alien kids, that glow-in-the-dark and look like trees, camping. The problem is, the town sheriff, already suspicious about Granny, is a scout leader camping in the same spot. Will David blow Granny"s cover, forcing the B&B to shut down for good, or will the intergalactic police have to intervene?
