When rumors begin to spread about the remaining white oak bullet, dangerous foes descend upon New Orleans in an attempt to take down Klaus (Joseph Morgan) once and for all. As the threats continue to grow, Elijah (Daniel Gillies) urges his siblings to lay low at the compound while Marcel (Charles Michael Davis), Vincent (Yusuf Gatewood) and Josh (guest star Steven Krueger) chase down a lead involving a mysterious vampire named Sofya (guest star Taylor Cole), who may have the answers they're looking for.
Meanwhile, tensions inside the compound build as Kol (guest star Nathaniel Buzolic) is forced to come face to face with his brother Finn (guest star Casper Zafer), the person responsible for his death. Elsewhere, Klaus and Hayley (Phoebe Tonkin) seek shelter with her former pack and stumble upon some unsettling news involving the threat against them.
