After her husband’s death, Diane has been a single mother to son Jake. She’s not ready to date but also doesn’t want to attend another work event alone, so her sister, Lori, suggests a rent-a-date service where Diane can hire someone to pose as her boyfriend. Diane meets her match, Miles, who is very charming and handsome. Diane knows it’s all an act but feels a connection with Miles’ fictional persona. But it soon becomes evident that Diane has rented a pathological liar with a disturbing dark past and no intention of leaving her.
