Lee Henning, the daughter of a Hollywood producer, a fragile, slightly awkward nineteen-year-old student with sad gray-green eyes, falls into the network of the Program - a powerful sect that manipulates its followers, completely depriving them of their will and emptying their wallets. Three months later, the parents, desperate to find their daughter with the help of the FBI, CIA, Los Angeles police and a private detective, turn to Tim Rackley. The specialist takes on this case in memory of his own daughter, who was killed a year ago. He goes to extreme measures - he himself joins the Program and becomes a slave of the Teacher.
