New high school graduate Grace and her best friend Emma are heading off to Paris for to fulfill Grace’s lifelong dreams. But when her mother and soon-to-be stepfather send Grace’s new stepsister, Meg, along to “supervise” the trip, the two friends are not so thrilled with their new, uptight counterpart. Undeterred, the three set off on Grace’s pre-packaged tour and itinerary, which proves to be much less than any of them expected. Just when they think Paris can’t get any worse, they discover that Grace has a doppelganger, in the form of an English socialite, Cordelia Winthrop Scott. They discover that Cordelia is leaving her hotel suite in Paris and tickets to a Monte Carlo charity function behind and heading off to Seville to see some friends. When Grace is mistaken for Cordelia at the hotel, she – with the support of her friends – decides to assume Cordelia’s identity and the three take off for Monte Carlo, where they discover friendship, love and their own hidden selves through the guise of another.
“Monte Carlo” is a coming-of-age story about losing yourself and finding out who you really are. Although the premise of the film revolves around Grace’s deception of all those around her, she does eventually see the error of her ways. Emma sits like the “bad angel” on Grace’s shoulder, telling her to take her fate in her hands and be Cordelia because she won’t be caught; meanwhile, responsible and uptight Meg is the “good angel” on the other shoulder and tells her that it’s wrong to be someone she’s not and enjoy all of the good things the deception would provide. While Grace chooses Emma’s side for most of the film, she struggles with her conscience, which eventually compels her to confess to Cordelia and the other wealthy socialites she’s come to know that she is, in fact, an impostor. Through her initial mistake, she learns the value of honesty. All three girls, through the experience, learn to more fully accept who they truly are.
