Calvin is on a mission to drive a train full of cocoa to a candy factory atop a mountain. Along the way, he encounters a number of situations that require him to be brave and kind and offer a helping hand despite his fear. In those moments, he touches the lives of those he meets and proves the purity of his heart. Once at the top of the mountain, Calvin meets a mysterious man who explains that God is always present, even in moments when we may think him absent, and by the time Calvin begins his descent, he's discovered the ever-present power of faith and prayer.
