Synopsis:
Several Kandorian’s have found a way to enlarge themselves to normal size and begin conducting raids on Earth. Superman follows them back to the bottle city of Kandor along with Jimmy Olsen to learn the reason for their attacks. When they arrive in Kandor, Superman finds that he is hated by the Kandorians. They now believe that Superman has been against restoring the city to normal size. To hide from the people, Superman and Jimmy assume the alternate identities of Nightwing and Flamebird, costumed after Batman and Robin.

Superman learns that the leader of the raiders and inventor of the new enlargement ray is Than Ol. The Man of Steel realized that the ray is flawed and will destroy Kandor, but Than Ol will not listen. Superman and Jimmy are able to escape Kandor with the help of Van Zee, but are unable to prevent Than Ol from enlarging Kandor in a remote location on Earth. As predicted by Superman, the city soon begins to disintegrate. Superman returns them to tiny size with Brainiac’s shrinking ray. The Kandorians are grateful that Superman has saved them and realize that he is indeed working in their best interests.
