When deadly conflicts emerge across the universe, it's up to Guy Gardner, John Stewart and an elite Green Lantern strike force to keep the peace – or else.
Guy Gardner and John Stewart try to get day jobs on Earth and it just doesn't go well. Later, the two talk about why they chose not to wear masks like Hal Jordan and Kyle Rayner do. They then go to Oa to find that someone is killing Lanterns and they volunteer to check it out bringing a group of ring slingers with them.
The enemy they face is unseen but has the ability to cut people, including Lanterns, in half without being seen. He/She also wiped out a whole planet by removing the water on a water based planet. When the Lanterns get to the planet they find two more Lanterns murdered and impaled on stakes.
