Plot

After the Geneva Convention, Viet Minh cadres are gathered to the North. There are also many who secretly stayed. Among them is Robert Nguyen Thanh Luan. He returns to Vinh Long, part of the diocese of Bishop Peter Ngo Dinh Thuc, who has known his Catholic family for long. The bishop adopts him into the Ngo family, where he begins associating with Ngo Dinh Nhu, the Vice President and Presidential Consultant of the Republic of Vietnam.
