Paul and his therapy dog Kathe have to lift a young patient from nurse Hildegard. Chris lost his mother in a helicopter crash and one side of his face has been disfigured by burns since then. The 19-year-old orphan only leaves his apartment at night, hidden under a hood. After complaints from the neighbors, his landlord, Stutter, gave him notice. The teenager flees from loneliness in fantasy worlds. With the support of Kathe, Paul would like to give him new courage to make his dreams come true. When he meets Helena while diving, hope grows that he will fall in love like everyone else his age. However, his fears make Chris hesitate to show himself to Helena - without a diving mask or hood.
