The Kardashians, Kim, Chloe, and Courtney, receive letters addressed to them from Hogwarts School of Witchcraft and Wizardry. Caitlin, a Hogwarts representative, arrives to take them to the school. Upon arrival, they meet Hermione Granger and are sorted into Gryffindor house. However, their behavior and attitude lead to them getting into trouble, including getting detention and losing points for Gryffindor.
The sisters participate in various classes, including flying lessons and potions, but their lack of discipline and disrespect towards their professors cause problems. They also encounter a troll and play a game of Wizards' Tic-Tac-Toe, which they win.
Despite their bravery in saving everyone from the troll, they are penalized for breaking multiple rules, and as a result, Gryffindor ends up with a negative score. Slytherin house wins, and the Kardashians are left to reflect on their behavior.
