In the Valley of Elah, director Paul Haggis's mournful dirge against the Iraq war, begins with a phone call: "Your son has gone AWOL." This is news to Hank Deerfield, who thought his son was still serving in Iraq. But evidently the boy's unit has just returned stateside, and young Mike Deerfield has disappeared from the base. Hank, a former Army MP, makes a few fruitless calls trying to track Mike down, and then piles into his beat up old Ford F-150 for the two-day drive to the base to find out what has become of him.
The answer is not a happy one. It's difficult to discuss the plot of In the Valley of Elah in any detail because it unfolds slowly. It's a good 20 minutes before we even learn of the crime, a murder, whose resolution will take up the bulk of the film. Hank, played with battered perseverance by Tommy Lee Jones, pulls at clues, knocks on doors, and runs into bureaucratic walls. He is aided, fitfully at first but with increasing generosity, by Detective Emily Sanders (Charlize Theron), a single-mom cop and oasis of decency in a police department otherwise populated by sexist dolts.
But while it has the shape of a detective story, In the Valley of Elah is something else altogether--a political parable, a moody polemic. The mechanics of the mystery itself are half-hearted: An early clue drawing on Hank's gift for multiplication is quickly forgotten; the evidence that finally unravels the mystery arrives in the mail, like a birthday present. And though the plot revolves around a soldier killed and mutilated, he is less man than metaphor: the American Dream, drawn and quartered. The question undergirding this film isn't whodunit but whatdunit, and the answer is the war.
