Anna Foster (MANDY MOORE) is the 18-year-daughter of President James Foster (MARK HARMON) and First Lady Michelle Foster (CAROLINE GOODALL) who's grown tired of her Secret Service protection, especially when it interferes with her dating life.
Thus, when the First Family heads to Europe for work, Anna wants to cut loose with her old friend, Gabrielle (BEATRICE ROSEN), the French Ambassador's now grown-up and wild daughter. Gabrielle is more than happy to help Anna ditch her detailed protection that includes agents Alan Weiss (JEREMY PIVEN) and Cynthia Morales (ANNABELLA SCIORRA).
She does so by getting a ride with British photographer Ben Calder (MATTHEW GOODE) who helps her elude the Secret Service. She appreciates his assistance and likes his cool attitude and demeanor, but doesn't realize that he's actually another Secret Service agent assigned to protect her. When the President gets word that Anna is with Ben, he orders that the agent continue his ruse as her new friend so that she can experience some freedom, albeit in a completely controlled fashion.
As the two make their way across Europe as accompanied by bohemian Scotty McGrath (MARTIN HANCOCK) -- with Weiss and Morales not far behind and starting to flirt with each other -- Anna and Ben start to develop feelings for one another. That development obviously puts Ben in an awkward position, as he must then balance his newfound feelings for her with his duty to the President, knowing full well that Anna will likely discover his ruse sooner or later.
