For farmer Earl McKnutt, life is pretty predictable. You wake up when its light; you go to sleep when its dark and in between you do the chores. If you're lucky, nothing ever changes. Earl's predictable life takes an unpredictable turn when a mysterious object crash-lands in his backyard. Together with his estranged and childlike brother Joel, the two go to investigate and in short order find themselves sifting through the remains of an exploded cow, fending off government agents and ultimately discovering the secret behind the mysterious object that has formed an enormous crater in their backyard. By the end of the night, Earl realizes that maybe a little mystery can be a good thing and a little adventure can keep you young at heart.
