Solo for Clarinet (1998)

In Berlin, Germany, a cruel murder takes place in an apartment building. Much of the victim's penis is bitten off; the victim loses a lot of blood before being struck on the head. Leading investigator Bernhard Kominka, already stressed-out by his problematic wife and their mentally-disabled son, seems to be the only one to see a lady in a red coat. After a while, his theory of her being the murderer might prove to be true, but he also sort of fell in love with this interesting new person in his life. Borders dissolve. Any decision he makes could prove disastrous.
