The official synopsis reads:

In order to show Elijah (Daniel Gillies) that her plan is what's best for him, Esther forces him to relive a time long ago when he loved a young woman named Tatia (guest star Nina Dobrev). With the help of Marcel (Charles Michael Davis), Hayley (Phoebe Tonkin) is determined to find Elijah, who has gone missing, but is torn when she discovers that Klaus (Joseph Morgan) is also in trouble. Elsewhere, Cami (Leah Pipes) finds herself in a dangerous situation when Mikael (guest star Sebastian Roche) takes her hostage as a way to lure Klaus to him, and Davina (Danielle Campbell) makes an upsetting discovery about Kaleb's (guest star Daniel Sharman) true identity. Lastly, a violent confrontation ensues when Klaus comes face-to-face with Mikael.

In the previous episode we saw Esther capture Elijah, and Mikael was injured by Klaus, who doesn't use the white oak stake on him, following Cami's advice. In the episode Hayley and Marcel are successful in saving all the werewolves from Esther's evil plans, thereby forming a bond of friendship between the two supernatural characters in New Orleans.
