Finally Non-Smoker - because dead! Anna Hawlicek hunches under her worn winter coat. She is on her way to her regular spot where she always buys cigarettes. Under the counter, of course. This time they are particularly cheap. And shortly after, she is dead. At the same time, a young Chinese man lies in the Vienna Prater meadows. Also dead. Someone has stubbed out a bunch of cigarettes on his torso. A coincidence of the cynical kind? Or an unwritten law that eliminates those who know too much? But why did old Hawlicek have to be the one to kick the bucket? Penny Lanz must go underground - a chilling showdown for the series favorite. Penny Lanz and her colleagues Helmuth Nowak and Carl Ribarski from SOKO Donau in Vienna smell trouble. Because what initially appears to be harmless heart failure of a chain smoker quickly reveals itself to be an opaque affair.
