The fourth episode of the children’s superhero series Isis premieres on CBS (sometimes referred to as Secrets of Isis), starring Joanna Cameron. The series is part of a live-action superhero programming block produced by Filmation. 
A classroom demonstration of a portable force field powered by a uranium pellet impresses Andrea’s friends, and intrigues the troubled student Bill, whose failure to win a recent science fair has left him without the means to buy a car. Desperate to overcome this obstacle, Bill steals the force field and offers to sell it to a local criminal, but rather than buying it from Bill, that criminal wants to pay Bill to be the one to use it. Worse yet, Andrea finds that the uranium pellet powering the device is leaking. Whoever has the force field device is in danger of radioactive contamination…but can she walk through the field by changing into Isis?
