A SENIOR PRANK NIGHT TO DIE FOR — Despite all that has happened, Caroline (Candice Accola) is determined to see that Elena (Nina Dobrev), Bonnie (Kat Graham), Matt (Zach Roerig) and Tyler (Michael Trevino) all enjoy a traditional Senior Prank Night before the school year begins at Mystic Falls High School. However, when uninvited guests show up, it doesn’t take long for the evening to take a deadly turn. Damon (Ian Somerhalder) convinces Jeremy (Steven R. McQueen) that he can use his new connection to the other side to help find a way to defeat Klaus (Joseph Morgan). Finally, Klaus deepens his hold on Stefan (Paul Wesley) and uses him for increasingly violent and dangerous purposes.
