In order to uncover what his old acquaintance Tristan (recurring guest star Oliver Auckland – Party Tricks) is really up to in New Orleans, Elijah considers attending a gala thrown by a mysterious group of ancient vampires known as the Strix, while Hayley invites herself to attend with him. There, Marcel is approached with an enticing offer made by a mysterious woman named Aya (recurring guest star Tracy Ifeachor – Strike Back, Crossbones), but he quickly realizes that things are not always what they seem. Elsewhere, when a vital component of Lucien's (recurring guest star Andrew Lees) plan goes missing, he and Klaus form a tentative alliance in order to find it.

While Klaus finds himself dealing with pressing matters at home, Elijah reluctantly aligns with Aya after learning that she may have knowledge of an elusive weapon that could kill an Original vampire for good. Meanwhile, alone and shunned by her coven of witches, a desperate Davina is left conflicted after she is approached with an enticing offer that could bring her one step closer to reuniting with Kol.

With the threat of the prophecy looming over their heads, Klaus and Elijah find themselves rendered useless inside a magical trap, while Aya and The Strix's coven of witches move forward with a risky spell that could take one of them down for good. Elsewhere, Freya leads the charge to get her brothers back and enlists the help of Marcel, Hayley and Stefan Salvatore, an old friend of Klaus', whose unexpected arrival may be the key to their survival. Finally, Davina moves forward with a dangerous plan that brings her one step closer to reuniting with Kol.

After learning that Cami's life is in danger and Aurora may be to blame, Klaus is forced to engage in another one of her devious games and follows a series of clues she's left behind for him. Meanwhile, Elijah, Freya and Hayley take drastic measures against Tristan when they discover he holds a valuable piece of information they need. Elsewhere, Aya gives Marcel an ultimatum that leaves him with a difficult decision to make, while tensions between Hayley and Jackson cause her to reevaluate her involvement in Mikaelson family matters.
