The Vow is adapted from a true story. The commencement of the movie is the scene that Paige Collins ( starring : Rachel McAdams) and her husband Leo ( starring: Channing Tatum) come out of a movie theater. On their way home, Paige unbuckles her seatbelt to lean over and kiss Leo. At that very moment, a truck collides their car from behind and Paige crashes through the windshield. In the meanwhile, Leo narrates words that "The moment of impact. The moment of impact proves potential for change." After this accident, Paige leaves in coma. When she awakes, she doesn't remember Leo as well as those sweet memories. Some people might think this plot is complete cliché. However, I think it really makes me feel touched. Also, it gives heart palpitations to fans of its charming co-stars Rachel McAdams and Channing Tatum. I really love their performance in About Time and Dear John while this one is the most incredible one.
