To keep Stefan from being harmed by Sloan and the Travelers, Caroline and Enzo agree to make a trip to Atlanta to find a newly discovered doppelganger. A terrifying turn of events at the Travelers' camp leads to the appearance of their mysterious leader, Markos.

Stefan and Elena have unsettling dreams of an alternate life they might have shared. Bonnie has a disturbing encounter with Grams. Luke shows up and explains what he knows about Markos and the Travelers. Matt has a terrifying encounter with those of the Other Side.

Enzo reveals to Elena, Stefan and Bonnie that he has learned what happened to the love of his life, and then, with the unwilling help of Liv and Luke, things take an ugly turn. Markos enlists Sloan's help in a ritual designed to break a curse against the Travelers.

When Tyler turns up at the Salvatore house with the news that Markos' plan to break the witches' curse puts Stefan and Elena in imminent danger, Damon suggests they hide out in a remote cabin. A ghostly presence at the cabin uses violence and fire to make itself known.

Sheriff Forbes is horrified when Markos uses violence to prove that Mystic Falls is now under the control of the Travelers. Finally, Damon's plan causes a huge explosion, and everyone is caught up in the mayhem, leaving a trail of heroism, sacrifice, relief and despair.
