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, bent on righting the wrongs of his family and fighting injustice.
To do this, he created the persona of the Arrow and allied himself with former military man John Diggle (David Ramsey), computer-science expert Felicity Smoak (Emily Bett Rickards), billionaire inventor Ray Palmer (Brandon Routh), lawyer-turned-vigilante Laurel Lance (Katie Cassidy), and his sister Thea (Willa Holland).
Uneasy alliances and rivalries will shift this season as Oliver faces his most difficult challenge yet.
As Season 4 begins, Oliver and Felicity's blissful getaway is cut short when Thea and Laurel pay them a visit and tell Oliver they need his help back in Star City. The city has been attacked by "Ghosts," assassins led by a dangerous man named Damien Darhk (guest star Neil McDonough).
However, when Oliver returns, Diggle makes it very clear that he doesn't want Oliver on the team.
