Synopsis:
While assisting the military with its testing of an airborne targeting system, Ray Palmer witnesses the disappearance of several paratroopers after the appearance of a UFO. Ray links the disappearance with that of Professor Alvin who goes missing while scuba diving with Jean Loring. Ray and frogman Jonah Wale investigate and are captured by aliens called Physalians. The aliens are using humans as hosts and taking them into nuclear power plants to gather energy. However, the radiation from the plants are killing the people. The Atom is able to save the possessed people and shut down the nuclear reactors which prevents the Physalians from feeding.
