After a violent shipwreck, billionaire playboy Oliver Queen was missing and presumed dead for 5 years before being discovered alive on a remote island in the North China Sea. When he returns home to Starling City, his devoted mother, Moira, much-beloved sister, Thea, and best friend, Tommy welcome him home, but they sense Oliver has been changed by his ordeal on the island. While Oliver hides the truth about the man he has become, he desperately wants to make amends for the actions he took as the boy he was. Most particularly, he seeks reconciliation with his ex-girlfriend, Laurel Lance.
As Oliver reconnects with those closest to him, he secretly creates the persona of the Arrow, a vigilante archer, to right the wrongs of his family, fight the ills of society and restore Starling City to its former glory. By day, Oliver plays the role of a wealthy, carefree and careless philanderer he used to be, flanked by his devoted chauffeur and bodyguard, John Diggle, while carefully concealing the secret identity he turns to under the cover of darkness. However, Laurel's father, Detective Quentin Lance, is determined to arrest Arrow for operating in his city. Meanwhile, Oliver's own mother, Moira, knows much more about the deadly shipwreck than she has let on and is more ruthless than he could ever imagine.
At the beginning of most episodes, a voiceover of Oliver Queen describes briefly the hardships that Oliver faced during his five years away from home. He states that as he has returned, he has decided to help out the people of his city, honoring both his father and his friend, respectively. However, beginning in the third season's "Al Sah-him", the monologue changed near the end of the season, briefly describing his crusade, but going on to mention his necessary ascension as the heir to the demon, Ra's al Ghul. In the fourth season, the monologue was changed, as he realize his old approach on bringing justice isn't enough, which leads him to become the Green Arrow. Season 5's monologue retains the crusade but also includes Oliver mentioning his double duty as Mayor and as the Green Arrow.
- "My name is Oliver Queen. For five years, I was stranded on an island with only one goal-- Survive. Now I will fulfill my father's dying wish-- to use the list of names he left me and bring down those who are poisoning my city. To do this, I must become someone else. I must become something else.
- "My name is Oliver Queen. After five years on a hellish island, I have come home with only one goal-- to save my city. But to do so, I can't be the killer I once was. To honor my friend's memory, I must be someone else. I must be something else."
- "My name is Oliver Queen. After five years in hell, I have come home with only one goal-- to save my city. Now others have joined my crusade. To them, I'm Oliver Queen. To the rest of Starling City, I am someone else. I am something else."
