 The Guardians Of The Universe hold sway on the planet Oa, and they contact test pilot Hal Jordan to alert him to the escape of Evil Star, an intergalactic super-criminal who wears a star-band on his wrist that gives him unlimited powers. Hal Jordan alerts his young mechanic Kairo, a lad from Venus, and quickly transforms into his true identity of Green Lantern, in time for Evil Star to attack Earth. After being beaten back by Green lantern, Evil Star fires across the universe to Oa, where a final confrontation ensues as the lord of crime seeks to wear out the 24-hour limit on the power of Green Lantern s energy ring.
