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 Pacific.

To do this, he creates the persona of the Arrow and allies himself with former military man John Diggle, computer-science expert Felicity Smoak, street brawler Roy Harper and international assassin Sara Lance, while keeping his secret from those closest to him including his sister Thea, who has allied herself with his most deadly enemy.
