Billionaire playboy Oliver Queen, missing and presumed dead after a shipwreck that claimed the life of his father, is discovered alive after five years on a remote Pacific island.
He is welcomed home to Starling City by his mother Moira, younger sister Thea, and best friend Tommy, but they sense he has changed. Oliver hides the truth about the man he has become, and tries to reconcile with his former girlfriend, Laurel, whom he cheated on with her sister Sara (who died in the shipwreck). While reconnecting with those closest to him, by night Oliver secretly masquerades as a hooded vigilante archer, attempting to fulfill his dying father's entreaty: to right the wrongs of his family, fight the ills of society, and restore Starling City to its former glory. Oliver's first task is to take down corrupt millionaire Adam Hunt, who has scammed millions from various people in Starling City. Laurel's father, police detective Quentin Lance, becomes determined to arrest the vigilante. Meanwhile, it is revealed Oliver's mother has an agenda at odds with her son, having orchestrated a kidnapping to determine what his father told him after the shipwreck
