Chu Yuan, at the age of 18, is under enormous pressure to demonstrate his competency as the future Emperor of Chu State. He must exercise caution in his actions, especially given the current turmoil along the Chu and Xinan frontiers. However, when Duan Baiyue—the young Xinan King—puts a stop to the revolt personally, the problem is lifted from his hands. His assistance saves Chu Yuan from unbearable sadness, and the people of Chu now revere Duan Baiyue as their hero. Two years later, Xinan's power has expanded, fueling speculation that Duan Baiyue plans to take over Chu State shortly. A angry Chu Yuan stands before a winter plum tree, unsure what to believe, and recalls a long-forgotten vow.
