When a young woman with a startling resemblance to John Andrew's wife Miranda appears days before her funeral, John Andrew MacGinnis begins an odyssey towards understanding. His son Donald is now Dawn, home to mourn her mother and repair the estrangement with her Dad. An ancient tractor becomes a focus for the mechanically-minded Dawn, but John Andrew's long-simmering resentments about the tractor heighten family tensions. As they restore the family tractor Dawn and her Dad cautiously rebuild their relationship and come to understand the mechanics of the heart. 　　译文(2): 当一个与约翰 · 安德鲁的妻子米兰达惊人相似的年轻女子在她的葬礼前几天出现时，约翰 · 安德鲁 · 麦克金尼斯开始了一场理解之旅。他的儿子唐纳德现在是黎明，家里哀悼她的母亲和修复与她的父亲的疏远。一台古老的拖拉机成为机械头脑的黎明的焦点，但约翰 · 安德鲁对拖拉机长期酝酿的怨恨加剧了家庭的紧张关系。当他们修复家庭拖拉机道恩和她的爸爸谨慎地重建他们的关系，并开始了解机械的心脏。
