A cowardly alien race called the “Boov”, led by Captain Smek, commence their “friendly” invasion on Earth. Relocating the humans, whom they deem as simple and backwards, to the Australian Outback, the Boov inhabit their homes. Oh, an accident-prone, free-thinking Boov, who is trying to fit in, decides to invite the other Boov to his apartment for a housewarming party, but no one comes. Meanwhile, 13-year-old Gratuity “Tip” Tucci, the only human who managed to avoid being taken during the invasion, alongside her Japanese Bobtail cat Pig, is trying to figure out where the other humans have been sent, desperate to reunite with her mother Lucy.
