A group of kids are enjoying a weekend at home with no parents around, turning their house into a battleground for fun, wrestling matches, and goofing off. Things take a sharp turn when a gang of older teens crashes the party, leading to chaos and tension. In the middle of all this, an alien spaceship crashes nearby, and the invaders start picking off the kids and teens one by one. Forced to put aside their differences, the kids team up to fight back against the aliens, using whatever they can find-homemade weapons, booby traps, and their own wild creativity. The story mixes wild, over-the-top action with a fast pace, focusing on friendship and bravery as the kids go all out to protect themselves and their home from the invading threat.
