Leo (played by Channing Tatum) and Paige (Rachel McAdams) are a loving couple. In a cold winter, a car accident caused Paige to lose her memory. When she woke up, she forgot Leo, whom she once loved deeply. Leo, who also loved Paige deeply, was unwilling to give up and tried to restore Paige's memory through various methods. He first persuaded Paige's parents to let her continue to live with him. At the same time, he helped her remember through various details. Their first meeting, their favorite restaurant, and her artistic creation. However, Paige, who lost her memory, also lost her creative inspiration and was ready to go back to study law as before. What's worse, Paige seemed to be ready to return to the arms of her ex-boyfriend Jeremy (Scott Speedman). Leo, who encountered setbacks again and again, seemed to see no hope of making Paige fall in love with him again. Will the story also develop to a tragic ending? Will Paige give up art to study law, which she doesn't like, just like she did before she met Leo? On another cold winter night, Leo and Paige's meeting again will tell us the answer. The film is adapted from a true story.
