Twenty-eight year-old Sienna Clark never intended to do much with her peaceful life outside of Monterey, California. With a steady job working at a local coffee shop and a passion for painting, she's content with the predictability of her everyday life.

Upon a chance encounter with a high-profile socialite, Sienna is presented with an opportunity of a life-time: an all-expenses-paid holiday around the world. After a fateful coin toss, Sienna finds herself packing a bag and flying first-class to Europe.

However, her new travel companion comes with more than his fair share of "unchecked baggage". With a lifestyle as demanding as his demeanor, their globetrotting adventures - and misadventures - have Sienna struggling to keep up.

With every stamp in her passport, she must come to terms with the new reality that life will never be quite the same... and neither will her definition of happiness and "home".
