It is prom time at Rosewood High School, with the exception of Alison, Aria, Emily, Hanna and Spencer who have been restricted because of “security” concerns. As the young ladies consider this to be the last embarrassing hit to their secondary school vocations, the young ladies’ moms attempt to make the best of a terrible circumstance by offering a home prom in Spencer’s stable. At first hesitant, the PLLs concur and attempt to make the best out of an awful circumstance. However, one to never miss a formal, Charles has different plans in store to make this a night they will always remember.
In the interim, Veronica, Pam, Ashley and Ella utilize prom night to meet up on everything that has happened to their little girls.
