After a violent shipwreck, billionaire playboy Oliver Queen (Stephen Amell) was missing and presumed dead for five years before being discovered alive on a remote island in the Pacific. He returned home to Starling City, welcomed by his devoted mother Moira (Susanna Thompson), beloved sister Thea (Willa Holland) and former flame Laurel Lance (Katie Cassidy). With the aid of his trusted chauffeur/bodyguard John Diggle (David Ramsey), the computer-hacking skills of Felicity Smoak (Emily Bett Rickards) and the occasional, reluctant assistance of former police detective, now beat cop, Quentin Lance (Paul Blackthorne), Oliver has been waging a one-man war on crime.
