A suburban family man inadvertently opens up a Pandora's Box of dysfunction, treachery, and murder while attempting to grow the perfect lawn, and run a family of raccoons off his property. Jeff (Tobey Maguire) and Nealy Lang (Elizabeth Banks) have an ideal marriage; they've just celebrated their 10th anniversary, they've got a spacious house in a nice neighborhood, and a newborn son to make their family complete. But Jeff has lost the ability to love his wife, and he's desperate to regain the spark that's made their marriage work for the past decade. His inner malaise growing deeper by the day, Jeff diverts his attention to nurturing a lawn that will be the envy of all his neighbors. One problem leads to another, however, when Jeff begins an obsessive mission to rid his yard of some unusually persistent raccoons, and has an unsettling encounter with his reclusive, feline-hoarding neighbor. Before Jeff knows it, a simple pest control problem has snowballed into a full-blown existential crisis involving bows and arrows, extortion, and multiple extramarital affairs.
