Arrow Season 4

After being gone for five years, during which he suffered unimaginable ordeals, billionaire Oliver Queen returned home to Starling City with a mysterious agenda and a set of new skills that he uses in a war on crime in this hard-hitting action series. Reinventing the DC Comics character for a modern-day audience, the Arrow is not a super hero ... but a hero -- every bit as formidable as the criminals he's hunting. Determined to right his city's wrongs and sworn to bring justice to those who have corrupted it, Oliver (aka The Arrow) -- with the help of former military vet John Diggle, the tech-savvy Felicity Smoak, billionaire inventor Ray Palmer, lawyer-turned-vigilante Laurel Lance and the newest member of the team, his sister Thea -- protects the people most in need and acts as a weapon of justice against those who prey upon them. Uneasy alliances and rivalries shift as Oliver faces his most difficult challenge yet -- facing Ra's al Ghul and the League of Assassins.
