Young Sarah's corpse is found in a lake, but actually died in a car crash and was clumsily dumped. She went missing during the youth club's “Geländespiel“ which she left after a row with other participants. Around was noticed a red model airplane, which she allegedly followed. Local 'weirdo' Karl Wagner possesses such one, and it was the passion of her long-gone father. The car paint trail from the crash leads not to Wagner but Mike Reichelt, who has a conviction for an earlier 'hit and run' car crash, which links surprisingly to Sarah's father.
