Spoiled billionaire playboy Oliver Queen is missing and presumed dead when his yacht is lost at sea. He returns five years later a changed man, determined to clean up the city as a hooded vigilante armed with a bow.
After many years in a sheltered rich-boy life, Oliver Queen is stranded on an island after his fathers yacht crashes and must learn to survive on his own. Five years later he is found alive and well after he was presumed to be dead. After he returns to his hometown of Starling City, he begins his crusade to rid it of nasty villains, drug dealers, mob bosses, and criminals by becoming an arrow-shooting vigilante.
Oliver Queen was stranded on an island for five years, undergoing experiences that changed and battle-hardened him. Eventually he makes it back home with a list of names of people who are corrupting his city, given to him by his father, who "isnt who he thought he was". Eventually, others join his crusade, which soon goes beyond the list of names. Then things get complicated.
