Wagner stars as professional tennis player Jaime Sommers, who becomes critically injured during a skydiving accident. Jaime's life is saved by Oscar Goldman (Richard Anderson) and Dr. Rudy Wells (Martin E. Brooks) with bionic surgical implants similar to those of "The Six Million Dollar Man" Steve Austin (Lee Majors). Through the use of cybernetic implants, known as bionics, Jaime is fitted with an amplified bionic right ear which allows her to hear at low volumes and at various frequencies and over uncommonly long distances. She also has extraordinary strength in her bionic right arm and in both legs that enables her to jump great distances and run at speeds exceeding 60 miles per hour. She is then assigned to secret missions as an occasional agent of the Office of Scientific Intelligence, while teaching middle and high school students in her regular life.
