As a caterer working on film sets, Dana Sterling feels like she’s at least adjacent to the industry she’s always wanted to be a part of, but serving people food isn’t the same as acting in a feature film. When a movie based on her friends falling in love is being made in New Orleans, she’s assigned to be a gofer to one of the lead actresses, a diva who seems impossible to please.
Samara Barber is an A-lister with a secret, headed to New Orleans to work on a small-budget indie film. This production isn’t exactly the blockbusters she’s used to, though, and not having her very specific requirements met makes her wonder if she made a mistake. Things can’t get any worse when the other actress in the film has to drop out at the last minute.
Dana’s dream might be about to come true when she’s called on to play the role, and maybe there’s more to the diva that is Samara, who’s never broken her one rule: never sleep with a co-star.
