Unbeknownst to the inhabitants of earth, an intergalactic police force known as the Green Lantern Corps serve as the peacekeepers of the galaxy. They congregate on the planet of Oa, where their headquarters is located. Each Lantern is armed with a mystical green ring that channels the will of it’s user to turn thought into reality. While doing battle with a fear mongering threat known as Parallax, Green Lantern Abin Sur flees his post after being mortally wounded. He crash lands on earth, where Cocky test pilot Hal Jordan (Ryan Reynolds) attempts to rescue him from his downed spacecraft. The ring chooses Jordan as Abin Sur’s successor.
