Edward Tustin, head of a group trying to take over Western Techtronics, engages efficiency expert, Dr. John Reardon of Executive Assistants, to have the four members of Techtronics who oppose his takeover killed. Reardon has hypnotized three girls for the job; Darlene Warren, Cynthia Weaver and Francine Miller. He uses motivational Pavlovian and Sensory conditioning and the subjects kill without fear, passion or memory. After the Chairman of the Board and a Vice President of Techtronics are killed and Francine Miller's body is found with them, the Angels are hired by company President, Steve Briggs. Briggs realizes he is next on the list. Kelly and Kris join Techtronics as executive trainees and Julie applies as Executive Assistant. She is hypnotized by Dr. Reardon, who uses flashing strobe effects, a candle and a water tank. After Julie has become completely programmed, she is sent to kill Briggs and almost succeeds when the suspicious Kelly and Kris arrive and save him. Julie is then deprogrammed by a doctor who explains that fire and water are two of the strongest hypnotic symbols. Reardon, Tustin and their associates are taken into custody.
