Prom Pact is set at the height of prom season. High school senior Mandy Coleman and her best friend, Ben, are surrounded by extravagant '80s-themed prom proposals. However, Mandy is focused on a different goal: her lifelong dream of attending Harvard. When she learns that her acceptance has been deferred, she is determined to do whatever it takes to get herself off the waitlist, even if it means asking for help from the one person she despises - popular all-star jock Graham Lansing, whose father is a powerful senator and Harvard alum. Once Mandy becomes Graham's tutor, she starts to realize that there's more to him than she thought, and perhaps there's something more to life than Harvard.
