Synopsis:
The Soviets wants to capture Ant-Man to learn the secrets of his size reducing formula. They dispatch Comrade X to execute the mission. A woman claiming to be Comrade X's ex-girlfriend then appears at a police station asking for Ant-Man's help. Through a network of ants, Henry Pym hears the request and responds. The woman reveals to him the plan to capture him.

The woman's information leads Ant-Man to a freighter with communists aboard. They capture him and prepare to take him home with them. However, Ant-Man is able to summon his ant friends to free himself. He then stops the ship and exposes Comrade X as Madame X, the woman who requested his help. Once the authorities arrive to take custody of the communists, Ant-Man departs.
