Car salesman Carl Resnick brings CBI the body of Mary Beth Hendricks (27), thinking it's a 'sack of potatoes': resulting from a masterly hypnotic suggestion. But was the killing conform to his deep desire or staged by the hypnotizer? She left her sister Lindsay's employer, Model Life, to work for leading hypnotherapist Dr. Royston Daniel's 'Neurolinguistic Programming' firm. His assistant Carl Resnick confesses to the killing, but Lindsay disputes this claiming Royston was Mary's lover, which he denies. Then another hypnosis complicates and ultimately clarifies everything.
