Synopsis:
Two aliens from the planet Krann appear in Superman's fortress and abduct the Man of Steel. The aliens have advanced technologies which they use to immobilize Superman and return with him to their home planet which has a red sun. They place Superman is a large machine which siphons off his super-kinetic energy as he tries in vain to escape. Oddly, Superman retains his super powers under the red sun. The aliens use the siphoned energy to reignite their planet's core to save their dying world.

Superman feigns his own death. The aliens remove him from his cage. This allows Superman to escape and reach the alien ship which brought him to Krann. He then discovers that Krann is actually a microscopic world within a dust particle in his fortress. Their red sun was actually a model red sun which explains how Superman retained his powers. With the mystery solved, Superman observes Krann as it explodes. The alien experiment to save their planet backfired resulting in its destruction.
