The movie is about a man (Leo Collins) and a woman (Paige Collins) who fell in love with each other. Their life together was perfect until they got into a car accident. The woman got a brain trauma as a result of which she lost a small part of her memory. She did not remember her husband at all. Leo tries to help Paige to remember all that was in their life before the accident. And he decides to re-conquer the heart of Paige again. Unable to get the love of his wife for the second time, he gives up. But in the end, after many trials, they come back together again.
Channing Tatum, who plays the main male role, was perfect. He is handsome and since the movie is mainly for girls he was a perfect choice. His character was gentle and very caring. In the middle of all the suffering he stayed patient and let Paige recover from the accident. But leading female act Rachel McAdams was not so great. They just did not look good together. In the beginning of the movie Paige was very likeable person but after the accident she changed in to a boring and annoying one. There was nothing to complain about the side characters.
The filming of the movie was good and professionally made. Music was chosen to the movie so that it fitted to different situations well. The film score, written and composed by Rachel Portman and Michael Brooks. The Vow is based on the actual relationship of Kim and Krickitt Carpenter, who wrote a book about their marriage, also known as The Vow. Chicago gets to show off in a number of shots, particularly in the Grant Park lakefront area, but most of the film was shot in Toronto.
