In a casino in a We'5t German health resort, one often sees Sybille - an attractive young student actress. With her winnings from the roulette table, she attempts to finance her studies. Despite a rather lucky streak, her winnings are a little on the lean side. She doesn't, however, gamble with her own money but with that of Dr. Busch, a lawyer, who likes to stay in the background with the argument that gambling houses are not the proper turf for a serious lawyer. From him, Sybille receives only a small share of her winnings later, and only through the intervention of Gerhard Fischer, a journalist, does Sybille come to realize her role in Dr. Busch's fraudulent scheme.
