A group of kids defend their Maine vacation home from knee-high alien invaders in this adventure comedy for the entire family. When Michigan native Bethany Pearson (Ashley Tisdale) arrives home after a secret outing with her boyfriend (Robert Hoffman), her father, Stuart (Kevin Nealon), decides that it's high time for a family vacation. Packing up the car with wife Hannah (Ashley Boettcher), teenage son Tom (Carter Jenkins), and big sister Bethany in tow, Stuart invites the extended family to join them at the vacation home for some much-needed R&R and sets his sights on Maine. Much to Tom's dismay, Bethany's stuck-up boyfriend, Ricky (Hoffman), even manages to wrangle an overnight visit. Shortly after the Pearsons arrive at their sprawling summer home, however, things start to get strange. As dark clouds start to swirl overhead, four glowing objects blast through the sky on a collision course with the Pearsons' roof. But these aren't your typical meteors, because inside dwells tough-talking alien commander Skip, muscle-bound weapons specialist Tazer, lethal female Razor, and geeky four-armed techie Sparks. Before long, the aliens have taken Ricky over via a powerful mind-control device, and announced their intentions to claim Earth for the "Zirkonians." While the adults are completely oblivious to the extraterrestrial threat, the kids fight to save the planet with a little help from Sparks, the alien tech-specialist and one nonhostile invader. John Schultz directs a script penned by British scribe Mark Burton (Wallace & Gromit).
