In 227 BC, the Wei army was ambushed by the Liang army in Phoenix Mountain. After the bloody battle, only the seriously injured Wei general (played by Wang Leehom) and the Liang soldier (played by Jackie Chan) who pretended to be dead survived. The general had the grand ambition to unify the countries, while the soldier just wanted to live his own peaceful life. The soldier captured the general alive, trying to take the general back to Liang State in exchange for five acres of good farmland and live a happy life without military service. On the way from Phoenix Mountain to Liang State, there were countless unknown risks in front and the mysterious team of Wei State was tracking behind. The soldier relied on the support of beautiful beliefs and his own cleverness to resolve the crisis again and again. However, when he arrived in Liang State, the soldier unexpectedly let the general return to Wei State. The soldier watched the general sailing away in a small boat by the river, but he didn't know that a drastic change had taken place on the land of Liang State behind him...
