Award-winning film by the director of 'Amores Perros', Alejandro González Iñárritu. Shot mainly with a hand-held camera, and following a non-linear plot line, the film captures the immediacy and confusion of the moments before, during and after a horrific accident that causes the lives of three disparate people to become interwined. Sean Penn plays Paul Rivers, a mathematics teacher facing up to his pending death from a heart problem, while his distant wife Mary (Charlotte Gainsbourg) hopes to become pregnant from artificial insemination. Naomi Watts is Cristina, mother of two little girls who has overcome a drug-dependent past to achieve a stable, happy marriage and family life. Benicio del Toro plays Jack Jordan, an ex-criminal who has now found Jesus and is struggling to provide for his wife and their two children in a poor area of the town. When tragedy strikes, all three characters must re-evaluate their lives in the face of death. The title refers to the 21 grams a person loses at the moment of death, thought to be the weight of the human soul.

Based on a soon to be true story Doc's reached the end of his endurance. Still mourning the loss of his wife and his world, the forty-something former college professor has fought to keep his daughter safe in a zombie-infested world. Now, the only escape for both of them seems to be the last two bullets in his pistol.

Joining a convoy of well-protected rednecks on a foraging mission offers Doc renewed hope, and their home base gives father and daughter the illusion of safety and civilization-enough that they can squabble like old times over Kate's infatuation with roguishly handsome young Jake.

The false sense of normalcy ends at the monthly group meeting being run by Tree the self absorbed leader of this small community who sees himself as the savior of humanity. His vicious and troublemaking half brother Tit makes a terrifying announcement and claims sixteen-year-old Kate for his own, an announcement that leaves Doc struggling to survive in "the pit," where those who anger Tree fight for survival against captured zombies.

If Doc's to save Kate, he's going to have to toughen up and form alliances within the group. And with a zombie herd closing in on the "Rednecks of the Dead," he's going to have to act fast, or risk losing the one person he still holds dear.
