As she rebuilds her life, two men enter her world: her mute brother-in-law Tusheng and A Long, a fellow soldier and her husband's close friend. Tensions rise as both men fall for her, while A Long is also loved by her sister-in-law, Xiaohua. Just as peace seems possible, war returns, and both men volunteer to fight, each willing to sacrifice himself for love and brotherhood.
