Lisa (Leslie Mann), Mitchell (John Cena) and Hunter (Ike Barinholtz) are three people who are not related at all, but they are closely connected by their children, Julie (Kathryn Newton), Sam (Gideon Adlon) and Kayla (Geraldine Viswanathan). The three girls are the best friends in school. The three girls who are about to graduate secretly made a plan to lose their virginity on the night of the prom. The three parents learned of this secret by chance, and the alarm bells immediately sounded in their hearts. So, the three decided to join forces to stop the stupid plan of the three girls, but the plan drawn up by these adults did not seem so smart.
