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. He soon learns that the man Deadshot (guest star MICHAEL ROWE) is taking out businessmen who are scheduled to bid at an auction on an energy company and Walter is one of the bidders. Realizing he can't protect his family and stop Deadshot at the same time Oliver enlists Detective Lance's help but his plan has dire consequences. Meanwhile Laurel and Tommy get caught in an awkward situation with Oliver.

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 realizes an innocent man, Peter Declan (guest star Lane Edwards), was framed by one of the targets on his list. As Arrow, he asks Laurel to help prove Declan’s innocence. Meanwhile, Walter asks one of his employees, Felicity Smoak (guest star Emily Rickards), to look into a $2.6 million withdrawal that Moira made without his knowledge.

A gang of bank robbers, dubbed The Royal Flush Gang, hits a local bank and seriously wounds an off-duty police officer during a heist. Diggle tells Oliver he needs to deviate from his father’s list and start helping the citizens of Starling City. Meanwhile, Tommy asks Thea for relationship advice, but things get awkward when she realizes he was asking about Laurel. Moira confronts Oliver about all of his recent disappearances in the middle of family functions.

In the first part of the epic crossover event with The Flash and Arrow, Barry is thrilled when Oliver, Felicity and Diggle join him in Central City to help stop a meta-human.

The Flash stops a robbery but the culprits get away after shooting a guard, and The Flash chooses to save the man instead of following the criminals. Joe shows Barry a book of suspects and Barry identifies Leonard Snart (Wentworth Miller) as the leader of the group. Snart revises his plan to steal the Kahndaq Dynasty Diamond and gets a boost when he gets his hands on a stolen "cold gun," which could kill The Flash. Dr. Wells is furious when he finds out that Cisco built the cold gun without telling anyone, and now it's missing. Meanwhile, Iris is getting the silent treatment from Joe because of her relationship with Eddie. Finally, The Flash and Captain Cold (aka Snart) have an epic confrontation.
