After a fatal shooting, Green Lantern Hal Jordan and new recruit John Stewart set out to prove it was an extraterrestrial event.

While John's middling errand ultimately proves eventful, Hal makes waves in Rushville – which only inspires him to dig deeper.

When his dad misunderstands a contact attempt from the Guardians, John is put forth as the next best option to fulfill the Green Lantern destiny. Then, after a lifetime of preparation, John finally gets his chance to interview for the Guardians.

As the 48-hour deadline nears, John develops a new theory about the Manhunter's location, leading him and Hal to run their next move by Sheriff Kane. Meanwhile, Hal's visit to Sinestro has consequences.

Now in business with his brother Marcus, John is on the verge of landing a major investor for his innovative take on panic rooms when an unexpected phone call pulls him back to Rushville - and everything he worked so hard to leave behind.

Finding themselves on another planet, Hal and John must put aside their fractured past to solve a murder. Along their journey, both men are forced to confront the ghosts of their pasts...and the ways their childhoods shaped who they are today.
