Synopsis:
A Navy ship destroys an iceberg which releases four frozen capsules. One of them breaks open releasing a plant menace which begin growing uncontrollably. The Challengers are called in to stop it. Prof is able to finish it off just before it drags the Navy ship underwater.

The Challs track the other capsules to a remote coastline. There, they find a strange corkscrew-nosed creature. They create a firewall which forces the creature to go underground. The Challs are summoned back to the coast to discover two dwarf-like aliens. The aliens explain that they came to Earth during the ice age and were frozen. Earth’s atmosphere is harmful to them and they are dying.

The Challs retrieve the fourth capsule which contains the alien ship. The ship contains tanks filled with the alien atmosphere which revives the aliens. The grateful aliens board their ship and pick up the other creature which has returned. Then they return to their own world.
