The movie revolves around the lives of two opposite high school teenagers: the daughter of a Baptist minister, Jamie Sullivan (Moore) and a jaded, aimless high school senior, Landon Carter (West).
When a prank on a fellow high-school student goes bad, Landon is punished by having to participate in various after-school activities, such as tutoring to younger children and acting in the school play. At these functions he meets Jamie, but does not befriend her immediately. When Landon realizes that he needs help for the play he asks Jamie to assist him. At school, however, Landon continues to look down upon Jamie and even mock her along with his closest friends.
Eventually, Landon is intrigued by Jamie's positive attitude, forgiving nature and overwhelming faith. Landon falls in love with Jamie even though she had previously told him not to. The two begin dating, which threatens Landon's reputation and friendships with other students. He defends Jamie on various occasions and decides to end connections with his previous clique.
Jamie finally tells Landon that she has a terminal medical condition and has stopped responding to treatments. As Jamie is hospitalized, Landon fulfills various wishes on Jamie's "Before I Die" list. Courtesy of http://en.wikipedia.org/wiki/ A_Walk_to_Remember_%28film%29
