Recovering alcoholic Chuck Dederich opens a storefront drug rehabilitation program that gains a following through its confrontational talk-therapy approach. As the program attracts non-addicts and celebrity followers, Synanon grows into a social movement that rapidly expands across the country.

By the 1970s, Synanon boasts its own farm, a school, and multiple businesses, but Chuck’s utopian vision begins to crack. As members face more extreme edicts, including mandates to quit smoking, separate from their children, and shave their heads – many find themselves weighing the benefits and costs of the choices they’re forced to make.

Chuck’s behavior becomes more belligerent and abusive. He forms a military-like boot camp for delinquent children where corporal punishment abounds. He mandates vasectomies and abortions and, when his wife dies, he quickly remarries and decrees that all current relationships must end so that everyone can find new partners. Many members divorce and remarry, which some of them later regret. TIME Magazine publishes “Swinging at Synanon” and Chuck sues for $76 million as his paranoia grows.
