Slade Wilson and Isabel make their move against Oliver, one to take Queen Consolidated, and the other to take Oliver down permanently!
When Frank Bertinelli is arrested, Oliver knows it’s only a matter of time before his daughter, Helena, AKA The Huntress, returns to town.
Following Slade’s return and his promise to make good on his threat to destroy Oliver’s loved ones, Oliver focuses all his energy on preparing for battle with his former friend.
Oliver is shocked when he learns that Slade has come to Starling City and is still growing in rage from the Mirakuru.
The team is investigating a villain named William Tockman, a.k.a. The Clock King, who is a brilliant thief armed with technology that can open any bank vault in Starling City.
As Laurel continues to unravel, Oliver and Lance try to convince Sara to stay in Starling City and finally reunite with Laurel and Dinah.
Arrow offers to train Roy so he can learn to control his newfound super-strength. However, Roy is a rebellious student and refuses to listen unless Arrow reveals his true identity, which Oliver refuses to do. Meanwhile, the Bronze Tiger (MICHAEL JAI WHITE) escapes from prison and steals Malcolm's earthquake machine to sell to the highest bidder. Oliver, Diggle and Felicity attempt to stop the transfer, but Roy gets in the way, putting everyone in danger. Laurel is disbarred and spirals out of control. Moira is thrilled when Walter (COLIN SALMON) asks her to dinner, but his reason surprises her. Thea encourages her mother to ask Walter to reconcile.
Arrow teams up with Laurel to find the man in the mask. Conflicted after Laurel reaches out to the Arrow asking him to investigate Sebastian Blood, Oliver is unsure whether to believe her accusations against the man he has publicly supported for mayor, but decides to trust Laurel. However, when the pair gets too close to the truth, Sebastian exposes Laurel's drug addiction and has her arrested. Meanwhile, Roy reveals his new super-strength to Sin who wants to test out his abilities. Unfortunately, Roy isn't able to contain his rage once unleashed and almost kills a man. Back on the island, Oliver is surprised when Sara reveals a secret about Laurel.
Oliver must tackle a new threat when bombs start to go off in Starling City. Felicity discovers the person setting them off is Mark Sheffer (guest star Sean Maher), a man who goes by the nickname "Shrapnel." Arrow discovers Shrapnel's next target is Sebastian Blood's "Unity Rally" and tries to talk the alderman out of hosting it, but he refuses. Arrow sets off to stop the bombing, but Shrapnel tricks him and traps him in a bomb-laced antique store where he is unable to move without setting off the device.
Oliver is visited by ghosts from the past. After a fight with Cyrus Gold AKA the Acolyte (guest star Graham Shiels), Oliver is drugged and left for dead. Determined to cure him, Felicity makes a risky decision. The cure causes Oliver to hallucinate, and what he sees forces him to confront his past. Meanwhile, Barry continues to help Felicity, and their connection grows stronger. The Arrow asks Lance to look into Gold, but when the stakeout on Gold goes bad, someone is killed. Roy is captured and tortured by Brother Blood (guest star Kevin Alejandro).
After a seemingly impossible robbery at Queen Consolidated, Central City’s police scientist Barry Allen (Grant Gustin) offers to help Oliver and his team.
Oliver is concerned when a mysterious illness sweeps the city, infecting hundreds of people — including Diggle. Oliver discovers Vertigo in Diggle's blood and realizes Count Vertigo (recurring guest star SETH GABEL) has broken out of prison and is once again distributing his drug. Meanwhile, Moira goes on trial for her participation in the Undertaking. When ADA Adam Donner collapses in court with Vertigo symptoms, Laurel must step in and try the case against Moira — leaving Oliver torn between standing by his family during the trial or catching Count Vertigo. The stakes change, however, when Felicity follows a lead and walks straight into a trap set by Count Vertigo.
Amanda Waller (guest star CYNTHIA ADDAI-ROBINSON) sends A.R.G.U.S. agents to kidnap Diggle. Waller informs Diggle that Lyla (guest star AUDREY MARIE ANDERSON) has gone missing after following a lead on Deadshot (recurring guest star MICHAEL ROWE) in Moscow. When Diggle tells the team he's headed to Russia to rescue Lyla, Oliver and Felicity decide to join, but things get messy when Isabel shows up on the tarmac and insists on joining Oliver's "work trip." Meanwhile, Moira's lawyer, Jean (guest star TERYL ROTHERY), tells Thea that dating Roy, a known criminal, is hurting her mother's case.
The Canary sings! While Oliver tends to the Canary's wounds, he tries to get her to talk about where she came from, but she refuses. But when Oliver and the Canary are attacked at the Queen mansion by a trained killer from the League of Assassins, she confesses to how she's connected with the nefarious group. Meanwhile, with Moira facing multiple counts of murder and conspiracy for her part in the destruction of The Glades, the Assistant District Attorney offers her a choice – plead guilty now and avoid the death penalty or take your chances in court. Thea begs her mother to fight for her life but Moira seems resolute about taking the offer. Meanwhile, Oliver is furious with Laurel for joining the prosecution's team on his mother's case.
Oliver meets the Canary. Oliver discovers a man who goes by the name "The Mayor" (guest star Cle Bennett) is bringing illegal guns in to The Glades, so Oliver sponsors a "Cash for Guns" event to help clean up the city. Unfortunately, The Mayor crashes the event with his gang and seriously injures Sin (guest star Bex Taylor-Klaus). The Canary is furious when she learns her friend is in the hospital and sets out for revenge. Meanwhile, Felicity stuns Oliver with a bit of information about the Canary's identity, Donner asks Laurel to dinner, and Diggle reconnects with an old friend.
Officer Lance's past puts Laurel in danger. Lance learns a criminal named Barton Mathis (guest star Michael Eklund), whom he put away years ago, broke out of prison during the quake and is back to torturing and murdering women. Felicity offers herself as bait so Arrow, Diggle and Lance can catch this villain, but the plan goes awry. Furious, Mathis kidnaps Laurel in retaliation and plans to murder her while Lance watches. Meanwhile, Thea and Oliver are stunned when District Attorney Adam Donner (guest star Dylan Bruce) seeks the death penalty for Moira. Oliver asks Roy to help him find the Canary (guest star Caity Lotz).
