Die schlafende Schöne.

Following a celebration held in honor of the winner of a violin competition, music professor Karin Landauer embarks on an erotic liaison with the winner's brother. When she returns to the bedroom from the bathroom, she discovers the young man murdered. Now, her infidelity can no longer be concealed from her husband—an internationally renowned violin virtuoso. However, the husband is far more devastated by the fact that a 300-year-old Stradivarius—"The Sleeping Beauty," which belongs to his wife—has vanished from their apartment, than he is by his wife's adultery.
