Trudie Chandler is an aspiring painter currently working as a restaurant waitress. With the pressure to please her parents building, she misses a job interview, gets dumped by her boyfriend Nick just before Christmas, and has a nervous breakdown. Stressed about going home for the holidays without a boyfriend, she kidnaps David Martin, a random customer at the restaurant, and introduces him to her parents as Nick. Trudie's family is vacationing at a very isolated log cabin away from anyone else, so David is unable to escape, although he makes several attempts. He finally decides to play along until the police come, but ultimately falls in love with Trudie and understands the family pressure that made her feel forced to kidnap him in the first place.
During Christmas dinner, the holiday comes to an abrupt end when Trudie's parents begin to fight, her brother Jake announces that he is gay, and her sister Katie says that she has quit law school and bought a Pilates studio with her parents' tuition money. The police then arrive and arrest the family during Christmas dinner, revealing that David is not actually Trudie's boyfriend. Before he was kidnapped, David had a successful job and a beautiful, rich girlfriend; however, during his time with Trudie and her family, he realizes his life has developed into something he did not intend. After the family is released (except for Trudie's grandma Dolores for attempting to resist arrest), when David decides not to press charges, Trudie does not see or hear from David for a few months, but learns that he will be engaged.
Trudie is invited to show her art at a local gallery, which her family attends, and she reconciles with them. She is stunned to see one of her pieces sold during the show. As she is leaving the show, she is kidnapped by David and taken to a nearby building. He tells her he bought the building and is making it into an architecture/art studio. He decided to turn his life around and do something he really loves: owning his own architecture business. His business also includes an art studio, and his first art piece is Trudie's painting, which he purchased. David admits his love for Trudie and Trudie admits her love for him as well, before they kiss.
