The half-orphan Luis grows up with his father, the ufologist Armin Sonntag. But he has no ear for the boy's worries and needs and also neglects the household, because he is completely obsessed with proving the existence of intelligent life in space. He doesn't notice that intelligent life is standing right next to him: his twelve-year-old son Luis! "... So there is a lot to laugh about when enjoying this imaginative film. It not only provides light-hearted pleasure, but also proves that nostalgia and a breath of fresh air in the UFO and alien subgenre of science fiction need not be irreconcilable opposites."
