Beirut, 1948. The Pelletier family returns. The Pelletiers are a prominent French family living in Beirut. The patriarch, Louis, has built a successful business manufacturing and exporting artisanal soaps. He hoped to pass the business on to his eldest son, Jean, but Jean doesn't have the sharpness or aptitude for such an enterprise. After nearly running the company into the ground, Jean marries a money-grubbing young woman who quickly makes him miserable, and they emigrate to Paris. But there's another reason Jean must leave - he has committed a terrible crime. His brother, Etienne, travels to Saigon, where he soon uncovers irregularities in the local currency office and begins investigating what he believes is a scheme to channel smuggled goods and cash to the Viet Minh. It is evidence that presents a real threat to his own life.
