In the past decade, meth labs in trailer parks, hotel rooms and farm sheds have sprung up across rural America to feed the nation's growing appetite for methamphetamines—a drug that is cheap, easy to make, and powerfully addictive. California produces nearly 80 percent of the nation’s meth supply, and more than half of it comes from the Central Valley. “Crystal Harvest” is a film about Modesto, a place once famous for its tomatoes and peaches, and now making headlines as a crystal meth center. How did this happen? The 26-minute documentary raises the question and looks for possible answers in the stories of four Modestans living on the frontlines of the rural drug war: a cop, a preacher’s wife, a Mexican farmworker and a meth-addicted prostitute. More than a sensationalized report about meth, “Crystal Harvest” is a story about friendship and forgiveness in California’s heartland.
