The earlier main storyline of the DC series Lanterns is set in 2016.
That storyline involves a murder in Rushville, Nebraska. Hal Jordan believes the case may be an extraterrestrial incident, bringing the Green Lantern mythology into an otherwise rural and grounded investigation.
Lanterns unfolds across two connected time periods rather than following one continuous timeline. The earlier period focuses on the case that begins the mystery, while the later period examines its continuing consequences.
The 2016 setting is not the earliest period explored in the abandoned Greg Berlanti version of the project. That earlier concept included stories set in 1941 and 1984, but those plans belonged to a different iteration of the Green Lantern series.
