Synopsis:
Professor Elias Weems is fired from his job because his employer thinks he is too old. Angry, Weems invents a device that can rapidly age people. He threatens to use his invention to gain revenge. Ant-Man tries to stop him and is turned into an old man. Weems then unleashes his device at City Hall, affecting many people including his own grandson. Ant-Man arrives on the scene and prevents Weems from accidentally destroying the device which can reverse the aging process. Seeing his own grandson turned into an old man, Weems regrets his actions. The aging is then reversed. All the old people are made young again. Ant-Man then acts as an advocate to get Weems his job back.
