Stanley, Harry, Sheila, and Beth have just finished their first year at Harrad College and share a special bond. Harrad College isn't an ordinary school; it conducts an experiment of putting male and female students in the same room and encouraging sexual freedom. Now that summer break has arrived, the four have decided to spend the vacation together. They will visit an old friend of Beth's, then spend two weeks visiting the others' families. However, they must fight against bias; not everyone is fond of Harrad College, and some only see it as an easy way for students to satisfy their lusts. Will the quartet's relationships and beliefs hold up under the constant pressure?
