21 Grams (2003)

In the nonlinear timeline style of Quentin Tarantino, '21 Grams' tells the story of Paul Rivers, a college math professor with heart failure, his wife's desire for a child, Jack Jordan, a reformed ex-con now working in a church, Cristina Peck, a seemingly typical housewife whose family is tragically killed in a hit-and-run. When Cristina consents to organ donation, her husband's heart is transplanted into Paul. Their lives intertwine as they navigate grief, guilt, and redemption.
