Flute and the team go undercover at a wedding to find the bouquet-catcher killer. While Flute argues with wedding crasher Harmony on who was the fun one in their relationship, Kang, Summers, and Wynona actually become a successful wedding band. But when Harmony catches the bride's bouquet, she becomes the target of the wedding murderer.

Flute and the team get the campy horror movie experience when, after a series of counselors are found murdered, they attempt to make the town's summer camp slasher-proof. Meanwhile, Harmony tries to get Stan outdoors and away from screens.
