After A-list actress, Alex Allen, has an epic Hollywood meltdown and is dumped on the red carpet before her latest movie premiere, she is in desperate need of some positive publicity in order to save her reputation as "America's sweetheart." Salvation comes in the form of a small town boy's video "Promposal" in which the student invites Alex to his high school prom. Sure enough, when the video goes viral, it scores the kid a date with his celebrity crush. It's also a chance for Alex, who was never asked to her own prom, to go back to high school and make this the best prom she never had. A Hallmark Channel original movie.
