Hardworking Australian nurse Ben Adams inherits a substantial sum and decides to tour Europe. In Monaco, the home of glamour and the idle rich, he meets French billionaire playboy Léo Artois. After getting off on the wrong foot—as happens when one accuses a stranger of being part of the Albanian mafia—their attraction blazes. Léo, born to the top tier of society, has never known limits, and Ben, used to budgeting every cent, finds it difficult to adjust to not only Léo's world, but also the changes wealth brings to his own life.
As they make allowances for each other's foibles, Ben gradually appreciates the finer things, and Léo widens his perspective. They both know one thing: this is not a typical holiday romance and they're not ready to say goodbye.
