As a Winter Wonderland-themed party fills the streets of Mystic Falls, Stefan (Paul Wesley) and Caroline (Candice Accola) find themselves at odds with Tyler (Michael Trevino) over his plans for Klaus (Joseph Morgan) and his hybrids. When Caroline proposes a solution to their problem, Hayley (guest star Phoebe Tonkin) finds a dramatic way to make it clear that she is not on board. Later, Klaus makes a discovery that leads to chaos and violence. Meanwhile, Elena (Nina Dobrev) and Damon retreat to the Gilbert Lake House to help Jeremy (Steven R. McQueen) conquer some dangerous inner demons with the help of Bonnie (Kat Graham) and Professor Shane (guest star David Alpay), who reveals a piece of ancient history that leaves them all speechless.
