In the season premiere, Oliver must transform from vigilante to hero. Diggle and Felicity travel to the island of Lian Yu in search of Oliver, who left Starling City after the devastation of The Undertaking and his failure to avert it. Convinced to return home, Oliver finds that things are in much worse shape than he imagined – Isabel Rochev (recurring guest star Summer Glau) is preparing a hostile takeover of Queen Consolidated, Thea refuses to visit Moira in jail, Roy 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 Oliver's mentors Slade (new series star Manu Bennett), Shado (guest star Celina Jade) and Oliver in a desperate situation.

DC Comics' Bronze Tiger and China White wreak havoc on the Glades. Oliver finds out that medicine being sent to Glades Memorial Hospital is being hijacked by thieves – and without an influx of supplies, the hospital will close. When Roy attempts to stop the thieves, he fails and is arrested by Officer Lance. Oliver gets into a heated battle with China White (recurring guest star Kelly Hu) and her new partner, Ben Turner, aka the Bronze Tiger (guest star Michael Jai White), over the supplies. Meanwhile, Laurel makes plans to catch the Arrow, and Thea gives Roy an ultimatum.

Heroes are forged and sacrifices made in this epic season finale as Oliver and Diggle race to stop the Dark Archer from unleashing his vengeance on The Glades. However, they run into a roadblock after Detective Lance picks up Felicity for questioning. Tommy and Oliver's already tumultuous relationship takes a turn for the worse after Oliver makes a confession about Laurel. After hearing of the danger in The Glades, Thea races to find Roy, inadvertently putting herself directly in the line of fire for Malcolm's devious plan. On the island, Oliver, Slade and Shado are locked in a life-or-death struggle against Edward Fyers (recurring guest star Sebastian Dunn) as his missiles lock on a full Ferris Air jetliner.

Recently released from prison, nefarious criminal Cyrus Vanch (guest star David Anders) 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. Meanwhile, Oliver shows Moira his father's notebook and questions her about the names on the list. Thea is miserable as she starts her internship with Laurel at the legal aid office; and Detective Lance makes a deadly mistake that puts Laurel in the crosshairs of Vanch.

Oliver and Diggle learn that Deadshot (Michael Rowe) is still alive -- and his next target is Malcolm. Malcolm invites Tommy to attend a benefit honoring Malcolm for his work with Starling City -- but Tommy refuses to attend. Oliver encourages his friend to mend his relationship with his father while he can. Meanwhile, Oliver struggles to balance his new relationship with McKenna with his duties as Arrow.
