The Huntress rides into Starling City and heats things up with Oliver. When Oliver encounters a mysterious woman, Helena Bertinelli (guest star Jessica DeGouw), daughter of mob boss Frank Bertinelli (guest star Jeffrey Nordling), he feels he can finally be himself -- but soon comes to realize she's hiding dangerous secrets of her own. Helena is on her own personal mission of vengeance and Oliver is caught in the middle. Meanwhile, Tommy is blindsided by an unfortunate turn of events and turns to Laurel for support.

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.
