Proměny nože (1970)

A young waitress, Dana, works in a roadside motel. She longs for the big, distant world, for beautiful things, and perhaps even for love. But her life is filled with various short-term relationships, her lover is a passing truck driver, a rich, elderly stranger, and random acquaintances who give her gifts. The girl does nothing to fulfill her dreams. Coincidence brings a group of students to the motel, and one of them, Martin, takes a liking to the waitress. A relationship develops that could perhaps lead to sincere love, to the fulfillment of her wish for a new life...
