A cool, badass vampire named Spike comes to Sunnydale intent on using the Hellmouth's energy to restore the health of his ailing love Drusilla. To prove his worth to the Anointed One, he offers to kill Buffy and add her to the two Slayers he has already destroyed. Buffy is forced to organise the Parent's Night at school and tries to keep her mom away from Principal Snyder. Unfortunately Spike and his new gang crash the party and Buffy must stop the ensuing slaughter while also keeping her mom and friends safe.
