After a violent shipwreck, billionaire playboy Oliver Queen went missing and was presumed dead for five years before being discovered alive on a remote island. When he returns home, those closest to him sense Oliver has been changed by his ordeal on the island.

Oliver heads to the courthouse to get his death certificate repealed and is pleasantly surprised to run into Laurel, who is there prosecuting Martin Somers, a criminal with ties to the Chinese Triad.

Oliver is surprised when someone shoots and kills one of his targets. As his plan is to bring people to justice vs. outright killing them, Oliver doesn't appreciate the help and searches for the gunman.

Oliver still hasn't figured out how to get back in Laurel's good graces, but a late night bonding session with Thea gives him the inspiration he needs. Looking into a suspicious murder case, Oliver realises an innocent man was framed by one of the targets on his list.

Oliver's confidence is shaken after being beaten by the Dark Archer and he takes a break from being Arrow. However, when Laurel calls Arrow for help investigating a firefighter's suspicious death, he reluctantly agrees.

The next person on Arrow's list is Diggle's commanding officer and mentor from Afghanistan, Ted Gaynor. Oliver suspects Ted is responsible for recent armoured truck robberies, but Diggle defends Ted and takes a job at Ted's security company to keep an eye on him.

Thea finds herself in trouble with the police after she gets caught using a drug called "Vertigo". Oliver thinks the only way to keep her out of jail is to find the dealer: a man who goes by the name of "The Count".

Recently released from prison, nefarious criminal Cyrus Vanch intends to re-secure his position as leader of Starling City's underworld. His first step is to take down his biggest opponent in the city -- Arrow.

After Oliver is shot, he turns to a surprising person for help -- Felicity. Diggle is stunned when he sees Felicity walk through the front door of the lair dragging a dying Oliver behind her, and the two team up to save Oliver's life.

Felicity tells Oliver he's all work and no play, so he asks Detective McKenna Hall on a date. A jewel thief named Dodger hits Starling City and targets someone very close to Oliver.

Oliver and Diggle learn that Deadshot is still alive -- and his next target is Malcolm. Malcolm invites Tommy to attend a benefit honouring Malcolm for his work with Starling City, but Tommy refuses to attend.

Deadshot returns to Starling City after taking down a U.S. Ambassador and six others overseas. By keeping tabs on A.R.G.U.S.'s manhunt for the assassin, Oliver, Diggle, and Felicity learn that a sting operation is underway to capture Deadshot -- alive.

Oliver focuses on crossing another name off the list. While digging through a crooked accountant's laptop, Felicity discovers a transaction that could help Oliver find Walter. To reconfirm the lead, Oliver gambles that Felicity can be counted on in the field.
