On an otherwise lonely summer vacation, the introverted Little Allan (11) is talked into acting as a human antenna for his old UFO-obsessed neighbor who thinks a huge invasion fleet from the outer space is on its way. But what they find is not exactly a huge invasion fleet. When the rickety antenna construction collapses, Little Allan is only barely saved by the alien girl Britney, who is doing a school project about the primitive human race.

Now Little Allan has to help her get home, while she becomes fascinated with this tiny example of the human species: Why does this boy keep saying that he is fine, even though his parents just got divorced, and he’s clearly not? Is that how all Little humans work?
