The Netherlands at the end of the '60s: Jan-Hein Swieps and his wife Ansje pick up the hitchhiker Manuel and can't get rid of him. After a night of drinking and debating about all sorts of things, Ansje falls in love with Manuel. Manuel stays a while with the couple, and in a short time the Swieps become party animals. But do they want this? It seems very difficult to the Swieps to get Manuel out of their lives.
