18-year-old Rebecca "Becca" Warner, the
valedictorian of her high school in a farm town in
South Dakota, has been accepted to a college in
Los Angeles. On her first day, she and her parents Walter and Connie meet Fred "Crawl" Weasel,
resident advisor of Becca's
coed dormitory. After they leave, the clash of cultures causes Becca to consider returning home, but Crawl convinces her to give the college a chance. She soon acclimates, cutting and dyeing her hair, dressing in a Californian style, and getting a
tattoo of a butterfly on her ankle. When Becca sees that Crawl has nowhere to go when school breaks, she invites him to South Dakota to celebrate
Thanksgiving with her family. When Becca and Crawl arrive in South Dakota, the Warners and Becca's boyfriend Travis are shocked by the changes in Becca. At dinner, Becca realizes that Travis wants to
propose marriage to her, and she urges Crawl to speak. Unable to come up with anything off the cuff, Crawl tells them that he has already proposed and she accepted. This upsets Becca's family and Travis, who punches Crawl in the face. Crawl expresses an interest in farming but bumbles through daily chores, to the amusement of Walter and his
farmhand Theo. However, Crawl proves himself as an avid farmer, quickly learning how to perform each task. He also impresses Becca's little brother Zack with his computer skills, and Zack begins to see him as a big brother. He compliments Connie's appearance and helps to bring her out of her shell for Walter. When Walter's father has a heart attack, Crawl performs
CPR and earns Walter's trust. While shopping for clothes, Crawl meets Becca's friend Tracy. Travis apologizes to Crawl for hitting him and invites him to a
bachelor party, where Tracy dances for Crawl. The next morning, Becca finds Crawl and Tracy waking up in the barn and furiously calls off the wedding, but Crawl and Tracy cannot remember what happened. Crawl leaves to head back to L.A. while Travis, who had been seeing Tracy on the side, berates her for behavior the previous night. Tracy finds her car seat left all the way back and discovers a bottle of pills underneath it. After picking up Crawl, who was attempting to
hitchhike, Tracy visits the Warner house to confront Travis and Theo while the Warners are sitting down to Thanksgiving dinner. Theo confesses that they drugged them and that he set them up in the barn. Walter immediately fires Theo. Becca stands up to Travis, and Crawl knocks him down, revealing that he had majored in
karate for two semesters. After Travis and Theo leave, Tracy is invited to sit with the Warners while Walter asks his son-in-law to cut the turkey. Becca tries to speak the truth about Crawl's proposal, but he stops her, saying that they have not decided on a wedding date and need to wait before making the decision, hinting that he intends to legitimately propose to Rebecca and have a proper relationship. ==Cast==
