This is it. Graduation. And Vic Navarro is throwing the most epic party Rancho Soldado has ever seen. She's going to pull off the most memorable good-bye ever for her best friends, give Happies-the kitschy restaurant that is her desert town's claim to fame-a proper send-off into bankruptcy, and oh yes, hook up with her delicious crush, Jake Zavala-Kim. She only needs to keep the whole thing a secret so that her archnemesis, Miss Ann Thrope, Rancho Soldado's nightmare Town Councilwoman and high school Economics teacher, doesn't get Vic tossed in jail.

With the music thumping, alcohol flowing, bodies mashing, and Thrope nowhere to be seen, Vic's party is a raging success. That is, until Happies fans start arriving in droves to say good-bye, and storm the deserted theme park behind the restaurant. Suddenly what was a small graduation bash is more like Coachella on steroids with a side of RASmatazz pie. The night is so not going as planned. And maybe that's the best plan of all.
