On a quiet and sunny summer vacation, the Pearson family moves into a charming cabin in a rural area, eager to enjoy a well-deserved break. However, what seemed to be an idyllic getaway quickly turns into an adventure beyond this world when they discover that their new home has an unexpected tenant: a group of mischievous little aliens planning to take over Earth.
The extraterrestrials, with their bright lantern-like eyes and playful demeanor, may seem harmless at first, but their intentions are anything but safe. The family, led by the clever and fearful son Tom, soon finds themselves forced to join forces to defend their home from these unwelcome visitors. To complicate matters further, the group must face a human antagonist: a ruthless security agent who is also after the aliens.
With a touch of humor and action, the family's bravery is put to the test as Tom and his siblings must work together and use their imagination to thwart the aliens' plans. Facing hilarious and dangerous situations, they will learn valuable lessons about teamwork, trust, and above all, the importance of family. As the adventure unfolds, the Pearsons realize that sometimes, the smallest beings can have a colossal impact.
