At fictional Harrad College students learn about sexuality and experiment with each other. Based on the 1962 book of the same name by Robert Rimmer, this movie deals with the concept of free love during the height of the sexual revolution which took place in the United States.
Oliver is in trouble. He's been caught embezzling money from his father's company, and unless he can pay back the $250,000 he took (which he can't), he will be fired from his job, arrested and probably sent to jail. Meanwhile, his rich wife has not only refused to bail him out of this mess, she's planning to divorce him. Desperate, Oliver thinks up a way out. He takes out an insurance policy on his wife with him as the beneficiary, then hires a hit man to kill her. The only problem is that because the doctor who performed the examination is an incompetent fraud, the insurance policy is invalid. Desperate to call off the hit, Oliver tracks down the hit man, only to find that he's subcontracted the killing to another hit man. Tracking down that killer reveals that he, too, has hired it out to a third person, and so on, and so on. Just how many people are trying to kill Oliver's wife?
Stanley, Harry, Sheila and Beth, four students from the 'free sex' Harrad College, spend the summer together to meet their families.
