The story opens with Superman trying to get to the core of a supernova. He is clad in a space-suit and is armed with an energy absorption unit. He tries to absorb as much energy as the unit can take. With this energy, he will restore the Kandorians, inhabitants of the Bottle City to their original size. The Kandorians are relatives of Superman and Supergirl, who were shrunk by Brainiac’s shrinking ray.
Superman’s absorption unit’s shielding melts away in the extreme heat and the unit charges itself fully. Superman goes away from the Supernova. But returning to Earth, he feels dizzy due to the radiation overdose and faints. He starts falling through the atmosphere, but Supergirl catches him in mid-air. When Superman comes to his senses, he shows her the unit and says that the energy it contains might be enough to restore Bottle City to its original size.
They come to the Fortress of Solitude. Superman speaks to the Kandorians via the com-link, telling them of his success in assimilating the energy needed for their restoration. The Kandorians thank him. But when one of them asks if the energy will be safe for them, Superman falls deep in thought. One Kandorian offers to volunteer himself for the test, but Superman refuses. He later talks with Kara, saying that he will subject himself to the test and will lure Brainiac into shrinking him. Then they go out.
The next day, Clark comes to his office to find it empty. Lois comes and takes him to Perry White’s 40th anniversary celebration. Other friends are relieves to see him. But in the middle of the function, suddenly the city starts shaking. Clark knows that Brainiac has come for him and slips away.
Superman flies out of the atmosphere and confronts Brainiac. Brainiac says that Superman’s sonic signal has brought him here. Superman tries to force Brainiac to use his shrinking ray, but the latter just employs his force-fields to shake Supes off. Superman hurls a meteorite towards Brainiac’s ship. This time Brainiac deploys his shrinking ray. He targets the meteorite, but superman destroys it and takes the full brunt of the ray. He shrinks to an ant’s size. Brainiac fails to understand superman’s ploy and tries to shrink him further. But Kara comes between them and fires a short burst of the enlarging ray. This deflects Braniac’s shrinking ray back to him, shrinking him and his ship into nothingness within moments. Superman and Kara fly back to their fortress.
Later, upon the Kandorians’ request, Superman and Kara fly them to a lonely planet under a red sun. Upon landing, superman places the bottle city on the ground and fires the enlarging ray at full power. Inside seconds, the city of Kandor is restores to its towering heights. Kara meets her parents, Zor-El and Alura, while Superman wishes that his parents were still alive to see this. But suddenly, the buildings start turning to disintegrating. They shimmer and turn to dust, disappearing completely.
Superman realizes that his enlarging ray was designed to work on animate objects only. One Kandorian hurls abuses at Superman. But another one, named Van-Zee stops him. He comes to superman and thanks him for restoring them to their original size. Superman requests to stay back and help them rebuild their city, but Van-Zee declines. He then punches superman senseless. He tells Kara that they insisted upon bringing them to this planet, because this planet appears briefly in the known universe, due to a shift in the cosmic axis. They are grateful to Superman and Kara for looking after them, but now they must learn to fend for themselves. He then bids the duo goodbye.
By the time Superman regains his senses, the unknown planet has already disappeared. Kara prays that the Kandorians live safely.
