Heather Coleman, self-titled as being quasi-engaged, has the perfect relationship with architect-on-the-rise Brett Miller. That is until she misses her flight to New York City for Christmas and ends up sharing a rented VW Bug with a stranger named Mark, an FBI agent that trouble always follows. One Week: She reasons that if people sit knee-to-knee on international flights, that it would be okay to catch a ride for only a few hours. They were supposed to get separate cars at the next town over... Not embark on a life-defining, love-inducing road trip. And Tomorrow: After meeting Mark can she settle back into normal? Get married? Was it just a fling or a sign of something wrong? Sit down and buckle up, Heather. It's going to get bumpy.
