Giordano is a young man from Milan who accepts a ride from a trio of Americans (an "open" couple and a homosexual) sightseeing in Italy. The husband is an older and worldly professor of archaeology while his wife is interested in exploring living things. The young hitchhiker is seduced by the beautiful wife, while her husband continues to gaze at ancient ruins.
