Synopsis:
Superman is trapped in a Kryptonite dust cloud in orbit around Earth. He manages to hitch a ride on a rocket that takes him out of the cloud and back to Earth. He makes another attempt to remove the dust cloud using a lead suit. The Anti-Superman Gang transforms the lead into glass before Superman can complete his mission.

Superman creates a flexible lead-glass suit which is virtually undetectable to the naked eye. Wearing the suit he tracks down the gang and pretends to be overcome when they spray him with Kryptonite gas. The crooks then cage the Man of Steel and try to kill him.

Superman pretends to be affected by the gas until he finds the machine that transforms lead into glass. He destroys the device, then ceases his pretense of weakness. After he apprehends the gang, Superman finishes clearing the Kryptonite cloud from space.
