Synopsis
''After a violent shipwreck, billionaire playboy 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, he protects his city with the help of former soldier John Diggle, computer-science expert Felicity Smoak, his vigilante-trained sister Thea Queen, former police captain Quentin Lance, and brilliant inventor Curtis Holt. But sinister players with a connection to Oliver's past will push the team to its breaking point, threatening everything Oliver's worked for and his legacy as the Green Arrow.''

''Newly appointed Mayor Oliver Queen finds himself challenged as he fights on two fronts for the future of Star City. With Diggle back in the military and Thea adamant about hanging up her hood as Speedy, Team Green Arrow is down to just Oliver and Felicity - but they're no longer the only vigilantes in town. Green Arrow's public defeat of Damien Darhk at the end of Season Four has inspired a new crop of masked heroes to step up and defend the city, though their painful inexperience makes them obstacles, rather than allies, in the field. The arrival of a deadly new adversary will force Oliver to confront questions about his own legacy, both as mayor and as the Green Arrow.''

Trivia

 * This is the final season of Arrow to feature flashbacks, regarding the five years Oliver was away from Starling City, later known as Star City; however, this will not be the final season of the series.
