After a violent shipwreck, onetime billionaire Oliver Queen was missing and presumed dead for five years before being discovered alive on a remote island in the North China Sea.  He returned home to Star City, bent on righting the wrongs done by his family and fighting injustice. As the Green Arrow, Oliver successfully saved his city with the help of his team including former soldier John Diggle, computer-science expert Felicity Smoak, former protégé Roy Harper, street-savvy Rene Ramirez, metahuman Dinah Drake, brilliant inventor Curtis Holt and Earth-2, Laurel Lance.

Following the untimely arrival of godlike being The Monitor, Oliver Queen left his home, his family, and his team behind to take on his most challenging battle yet, knowing the cost may be his life. But this time it's not just his city he's seeking to protect – it's the entire multiverse: everything that ever was or ever will be. In ARROW's eighth and final season, Oliver's quest will send him on a journey where he is forced to look back at his years as the Green Arrow and confront the reality of the ultimate question: what is the true cost of being a hero?
