Movie plot title: 21 Grams Movie plot: "21 Grams" is done in the Quentin Tarantino "all the scenes are out of order" style, which is a good way to tell this story.Paul Rivers (Sean Penn) is a college math professor and a long-time smoker who is close to death from heart failure. He's weak, coughs and gasps, and drags around an oxygen tank to help him breathe. He's on the transplant list for a new heart. His wife wants nothing more than to get pregnant by him before he dies.Jack Jordan (Benicio Del Toro) is an ex-con that has spent more time in jail than out, but has reformed and is working in a church, spreading the gospel, and helping kids that are heading toward the same kind of trouble he's been in. He and his wife have two young children.Cristina Peck (Naomi Watts) seems to be a typical housewife. She and her husband have two young daughters, and they appear to have an ideal life.One afternoon Jack accidentally runs over Christina's husband and daughters while they're out walking. Both of the little girls are killed, and the father ends up brain dead. Christina consents to organ donation, and her husband's heart ends up being transplanted into Paul.Jack turns himself in for the hit-and-run and goes to jail, but is later released. Paul recovers and hires a private detective to find the donor family (to find out "who he is"). The detective comes up with the information not only about the donor and his widow, but also about the ex-con. Most of the movie is about the relationships that develop between these three main characters.

Movie plot title: The Silence of the Lambs Movie plot: FBI trainee Clarice Starling is pulled from her training at the FBI Academy at Quantico, Virginia by Jack Crawford of the Bureau's Behavioral Science Unit. He assigns her to interview Hannibal Lecter, a former psychiatrist and incarcerated cannibalistic serial killer, whose insight might prove useful in the pursuit of a serial killer nicknamed "Buffalo Bill", who skins his female victims' corpses. Starling travels to the Baltimore State Hospital for the Criminally Insane, where she is led by Frederick Chilton to Lecter's solitary quarters. Although initially pleasant and courteous, Lecter grows impatient with Starling's attempts at "dissecting" him and rebuffs her. As she is leaving, one of the prisoners flicks semen at her. Lecter, who considers this act "unspeakably ugly", calls Starling back and tells her to seek out an old patient of his. This leads her to a storage shed where she discovers a man's severed head with a sphinx moth lodged in its throat. She returns to Lecter, who tells her that the man is linked to Buffalo Bill. He offers to profile Buffalo Bill on the condition that he be transferred away from Chilton, whom he detests. Buffalo Bill abducts a U.S. Senator's daughter, Catherine Martin.
