Rachel McAdams is the character of Paige Collins. Her husband is Leo (played by Channing Tatum). On the way driving home from a night out, they are hit by another car. The accident causes Paige to lose some of her memory after she revives. Paige cannot remember the most recent things in her life starting back to about two years earlier at a time when she had a fight with her parents.
She wanted to go to art school and her parents wanted her to go to law school. She left her home at that time and did not speak to her parents after that. She also called off her engagement with Jeremy (played by Scott Speedman) and ended up marrying Leo instead. The problem is, that because of the accident, she cannot remember any of this. Her doctor tells her that her memory may come back if she returns to her normal routine. But nothing feels normal to her at all. Leo and Paige's parents fight over helping her. Paige decides to go home with her parents because she can remember who they are and she has no memory of her husband Leo at all. Leo is confused and depressed that his wife, who he loves so much, cannot remember him.
To make matters worse, pretty much all of Paige's memories are before the time she left law school to become an artist. She cannot remember why she left the law school or why she broke up with Jeremy who obviously still wants to be with her, because when Jeremy realizes what is happening he breaks up with his girlfriend to have a second chance of marrying Paige. When Paige sees Jeremy she remembers liking him and kisses him. Leo visits Paige but since he doesn't know her family or her old friends at all, he does not fit in. Paige's parents want their daughter back at any cost, so they convince Paige to divorce Leo. They even convince her to eat meat as her favorite food even though they know she had changed to be vegetarian. Leo shows her the artwork she made, but she doesn't remember making any of it.
Paige goes back to law school, and divorces Leo. While at law school, her mind drifts in class. She begins sketching which starts the same cycle over, of why she left the law school in the first place. Then she breaks up with Jeremy needing to find herself on her own. To her surprise in her things, she finds where she wrote down the vow of lasting love she made to Leo. This stirs her true memories of him. They start over dating, as if they have just met.
Best part of story, including ending:
The effects of amnesia on Paige are very interesting, in seeing what she can remember and the parts that are missing from her memory.
Best scene in story:
Of course the best scene is when she finds the vow she has written, because it is the first physical proof of her true love for Leo.
Opinion about the main character:
There is only empathy for Paige, because everything that happens to her is so confusing and none of it is her fault. I also like that film this was based on a true story.
