As part of the DC New 52 event, the Green Lantern Corps return, led by fan favorite Lanterns Guy Gardner and John Stewart. When the Alpha Lanterns, an internal police force for the Corps, arrest Green Lantern John Stewart for the murder of a fellowLantern, it sends shock waves throughout the entire Corps. It is up to Guy Gardner and the rest of the Green Lanterns to break Stewart out and bring down the emotionless Alpha Lanterns.
