Martin is extremely interested in aliens. Every week he finds a place to sit and study the sky for UFOs (Unidentifed Flying Objects). One day, deep in the forest, he accidentally meets Lene, a vain girl from school. She is on her way to a party, but has got lost. Suddenly a lightning object flies across the sky, towards an abandoned house in the forest. In spite to Martins warnings, Lene runs into the house, and Martin must protect her from the mysterious visit.
