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.

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.

As Oliver and Helena grow closer, Oliver trains her to be his ally, complete with showing her how to use a crossbow. Diggle disapproves of Oliver sharing his secret with Helena as he's not sure she can be trusted, but Oliver refuses to listen to his concerns. When Helena's quest for revenge proves to be too strong for Oliver to handle, she kills the head of the Triad and all hell breaks loose.
