This film offers us a juxtaposed journey of two priests: Father Van Ban, a Vietnamese priest from the parish of Thy Hu in the Hé region, who after nine years of training in Paris decides to return to Vietnam, and Bernard de Terves, a young deacon from the Foreign Missions of Paris who decides to leave for China after his ordination. Their intersecting paths allow us to address themes related to East-West intercultural dialogue, particularly that of transmitting the Gospel message.
