Before any other sentient beings existed in the universe, a race of beings calling themselves the Guardians of the Universe harnessed the power of the green element, the greatest power in the universe, to create the Green Lantern battery. However, the battery has a flaw: the color yellow, the one part of the light spectrum that can resist green. The most concentrated source of yellow energy, the yellow element, was hidden by the Guardians to prevent others from using it against them.Ferris Aircraft's test pilot Hal Jordan (Christopher Meloni) is recruited to join the Green Lantern Corps after the death of Abin Sur. He is placed under the supervision of respected senior officer Sinestro (Victor Garber), who is investigating Abin's murder. Abin was killed while doing an undercover investigation of Kanjar Ro (Kurtwood Smith), who managed to locate and steal the yellow element. What no one realizes is that Sinestro provided Kanjar with the location of the element, in order to have it fashioned into a weapon of comparable power to the Green Lantern battery.
