While earning a living as a Wild West show performer, former rodeo rider Ace (Michael Madsen) bonds with an orphan girl named Jennie (Bella Thorne) and soon finds himself playing the role of father figure. In time, they form a makeshift family that includes Ace’s ex-fiancée. Louis Gossett Jr. also stars in this first-rate drama that takes its title from the classic Hoagy Carmichael tune “Ole Buttermilk Sky.”
