A hostage situation in Ivy Town, that is an apparent diversion for a break-in in Ray's lab, causes Ray to recall his childhood, his brother Danny, his uncle David, and his use of a meteor containing dwarf star matter to shrink himself and start his career as the Atom. But when he searches through the wrecked lab, Ray finds a clue that suggests the culprit and leads to a shocking discovery.
