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, hell 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, former police captain Quentin Lance, and brilliant inventor Curtis Holt (Echo Kellum) and a new team of vigilantes-in-training. 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.
