The film follows Harrad College students Stanley, Sheila, Harry, and Beth as they spend summer vacation together to get to know their families.

The film picks up with the four main characters—Stanley, Sheila, Harry, and Beth—deciding to spend the summer together, traveling and exploring the outside world beyond the experimental environment of Harrad College.

The group embarks on a road trip, hoping to put into practice the lessons they learned about love, sexuality, and relationships.

Harry and Beth's relationship is put under strain as they confront the realities of jealousy and possessiveness, which were not as evident in the controlled environment of the college.

As the summer progresses, the characters experience moments of personal growth and revelation, but also face the harsh realities of their differing expectations and desires.
