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.

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, meta-human Dinah Drake, brilliant inventor Curtis Holt and Earth-2 Laurel Lance. In last season's finale, in the wake of discovering what his future holds, Oliver must leave his friends and family behind him and will find himself pit up against his most challenging battle yet, one that will leave the multiverse hanging in the balance.
