Paige and Frankie become the Promposal Masters of Sierra High until a lofty promposal ask from Bernie jeopardizes their perfect record AND their friendship.
Paige and Frankie help their fellow students to ask people out for prom by putting together elaborate prom proposals known as "promposals". Paige and Frankie have successfully helped nine children get dates for the prom, but they are worried about disrupting their winning streak when Bernie asks them if they can get him a date with Kate, a tall tennis player who is an honor roll student and the president of her class. Paige and Frankie do not believe Kate would want to go to prom with Bernie, so they have Amelia ask him instead to spare him of public rejection. After Bernie learns the truth, Paige and Frankie decide to proceed with a promposal for Kate. Bernie eventually gets a date with Kate on his own, but because of his clumsiness, he inadvertently disrupts the prom and hurts Kate. Meanwhile, Dirk tries to avoid hearing spoilers about the season finale of a television series until he can watch it with his brother. However, Amelia and Viking Guy repeatedly discuss the finale while Dirk is around. After Dirk watches the finale, he learns that Amelia and Viking Guy are no longer interested in discussing it as they have begun watching a new television series.
