Kim Sơn

In 1955 Tay Ninh, the National United Front is established and gives Ngo Dinh Diem's government an ultimatum: reform or attack. Luan continues to handle his new rise of popularity within sociopolitical circles in South Vietnam. He goes to Da Lat for a vacation, where a meeting between him and a young woman has been arranged.

As the new government takes over South Vietnam following the Fall of Saigon, civil engineer Dương Tấn is fearful of imminent repression. He and his colleagues are dispatched to fix a hydroelectric plant where they meet Đỗ Long, a bubbly engineer from the North.

In 1963, amidst tense relations with Buddhism that may face international backlash, the Ngo family try to find a way around the situation, calling on Luan for missions worth his life. Saigon is heated. A coup may be under preparations. Tran Le Xuan goes on a diplomatic tour of Western nations, determined to clear names.
