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.
When he returns home to Starling City, his devoted mother Moira (Susanna Thompson), much-beloved sister Thea (Willa Holland) and best friend Tommy (Colin Donnell) 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's become, he desperately wants to make amends for the actions he took as the boy he was. Most particularly, he seeks reconciliation with his former girlfriend, Laurel Lance (Katie Cassidy).
As Oliver reconnects with those closest to him, he secretly creates the persona of Arrow - a vigilante – 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/bodyguard, John Diggle (David Ramsey) - while carefully concealing the secret identity he turns to under cover of darkness.
However, Laurel's father, Detective Quentin Lance (Paul Blackthorne), is determined to arrest the vigilante operating in his city.
Meanwhile, Oliver's own mother, Moira (Susanna Thompson), knows much more about the deadly shipwreck than she has let on – and is more ruthless than he could ever imagine.
As Season 2 begins, Diggle and Felicity (Emily Bett Rickards) travel to Lian Yu in search of Oliver (Stephen Amell) who left Starling City after The Undertaking.
Convinced to return home, Oliver finds that things are in worse shape than he thought - Isabel Rochev (guest star Summer Glau) is preparing a hostile takeover of Queen Consolidated, Thea refuses to visit Moira in jail, Roy (Colton Haynes) is trying to fill the void left by the Arrow's absence, and Laurel is working with the District Attorney's office to take down the vigilante.
Meanwhile, flashbacks to the island show Slade (Manu Bennett), Shado (guest star Celina Jade) and Oliver in a desperate situation.
Season 2 stars Stephen Amell as Oliver Queen, Katie Cassidy as Laurel Lance, David Ramsey as John Diggle, Willa Holland as Thea Queen, Emily Bett Rickards as Felicity Smoak, Manu Bennett as Slade Wilson, Colton Haynes as Roy Harper, with Susanna Thompson as Moira Queen and Paul Blackthorne as Detective Quentin Lance.
