When Dr. Claw returns, Inspector Gadget is brought out of retirement to defeat him again, now with Penny and Brain's open participation.

After being missing for years, Dr. Claw is revived by his nephew Talon with designs of conquest once again. In response, HQ calls Inspector Gadget out of retirement to face this menace. Fortunately, his niece, Penny, and his dog, Brain, are also able to help him once again. However, they are now official junior partners who can operate in the open at last, which is all the better considering the Inspector is just as clueless as ever.—Kenneth Chisholm ([email protected])
