Grace Reynolds has been playboy Brennan Wolf’s PA for the last three years. After a brief one-sided crush, Grace has spent the better part of her time shaking off his overzealous one-night stands and helping him dodge calls from his family. After losing her mother, she decides she’s had enough of managing Brennan’s private life. She hands in her notice, which somehow ends with her agreeing to be Brennan’s fake fiancée at his sister’s wedding. She just has to get through the weekend and she’ll be free. Only life never goes exactly as planned, and as the line between fake and real gets blurred, who is fooling who?
