Nora Mackenzie's entire career lies in the hands of famous NFL tight end Derek Pender who also happens to be her extremely hot college ex-boyfriend.

Instead of giving in, Nora starts a scheme of her own. But then a wild night in Vegas leads to Nora and Derek in bed the next morning married. With their rule book out the window, could this new relationship be the thing to save their careers?
