Harald is an alien tourist who visits the earth on a three week package tour. As he bought the cheapest ticket, he only got a very ordinary guest body. Nevertheless he tries to learn as much as possible about human life and thus tries to get into contact with Rica. When she realizes that Harald`s wired story about being an alien is true she gives him shelter in her house. When Harald meets Rica`s ex-boyfriend Friedo and a couple of Rica`s friends, he starts lots of confusion as he is notoriously honest and never lies to be polite. Also, his fear of the dark causes various misunderstandings.
