In order to show Elijah 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. With the help of Marcel, Hayley is determined to find Elijah, who has gone missing, but is torn when she discovers that Klaus is also in trouble. Elsewhere, Cami finds herself in a dangerous situation when Mikael takes her hostage as a way to lure Klaus to him, and Davina makes an upsetting discovery about Kaleb's true identity. Lastly, a violent confrontation ensues when Klaus comes face-to-face with Mikael.

When Klaus discovers that Elijah has been afflicted by Esther's magic, he heads to the bayou in search of an antidote, but quickly realizes he's not alone. Armed with intel gathered by Aiden, Hayley teams up with him, Marcel, Cami and Josh and launches a plan to take down Vincent by exploiting his one weakness. Meanwhile, with Esther determined to carry out her plan, Vincent and Kaleb are forced to reconsider their own strategies. Intrigued by Davina's unwavering attempts to create an unlinking spell, Kaleb lets her in on some secrets from his past and brings her to a place he frequented in 1914.
