I never want him to find out that under this mask is just boring old me!

Carlie, a diligent teacher, is dragged to a costume party in a daring outfit her friend made her wear. At the party, she is persistently pursued by Tyler, a known playboy. Tyler is her friend’s brother-in-law, but he doesn’t realize that it’s actually "boring old Carlie" under the mask. Knowing she’d normally never have a chance with a guy like him, Carlie happily allows herself to be seduced. The next morning, Carlie leaves without revealing her identity and Tyler becomes determined to find the woman in the mask!
