Lin Hsiang and Lin Cheng are brothers whose lives were turned upside down by an accident that took place in the mountains on their indigenous reserve. Cheng goes to prison for killing their father, while Hsiang successfully becomes a doctor and serves their village. Several years later, Cheng is released from jail, bringing turmoil to Hsiang’s ordered life. Cheng wants to go back to the forest where the accident occurred, but Hsiang is considering conceding the forest to mining companies. Their conflict escalates. Meanwhile, Hsiang’s wife, Yi-Wen, discovers her husband was the actual killer, but Cheng became the scapegoat for his brother’s crime at their uncle’s insistence. Yi-Wen realises that her husband is not as perfect as she thought, and Cheng is not as rough as he seems. In the end, the two brothers return to the forest to resolve their conflicts over the land, their father, and Cheng’s unfair prison sentence, hoping for a better outcome. Can they recover their lost brotherhood at the very place where their discord began?
