As a cosmic radiation storm approaches the planet, but Don is confident because Dr. Smith had been assigned the task of installing cosmic arrestors, but Judy tell him that she has seen them still lying on a pile of equipment. Don confronts Smith and insists he begin the job before it is too late. Meanwhile, Penny is missing and the adults fan out to find her before the storm strikes. Penny, out for a walk, has come across a large, ornate mirror. Smith finds her just as the storm strikes and they take shelter underneath, unaware that the cosmic radiation is having some effect on the mirror. After the storm has passed, John finds the pair at the mirror, but Smith insists he not investigate, saying it is only worthless trash. In fact, Smith suspects the mirror’s frame is made of platinum.
