Das morphus Geheimnis (2008)

Never until the end of their days - so swears a mysterious group - will they reveal the secret location of Beethoven's will. For this is where his magical Morphus composition is hidden, which puts anyone who hears it into a deep sleep. Generations later, this confidential knowledge has been passed down from a great-great-great-grandfather to a favorite grandson. And he has discovered how to use it to make a profit. Together with his crook friend, he is just about to get hold of the notes when he is interrupted by the unsuspecting and shy Nicki. The Morphus secret ends up in Nicki's pocket, of all places, in the hustle and bustle of the chase that ensues. Nicki and his father arrive at a completely snowed-in hotel, an old castle.
