n 1960, in Cambodia, the General MCHULPICH, commandant of the armed forces of Siem Reap province and Kompong Thom, wants, by making an alliance with the USA, to separate these provinces from Cambodia. In order to stop the project of the ambitious MCHULPICH, the leader of the staff officers of the royal Khmer Army, nominated the Prince Admiral DHANARI, head of the counterespionage to take care of these mission.
On the way to Phnom Penh, the Prince, whose car has broken down, is helped by the ambassador, she just came into function in the country. The Prince, openly criticized for his anti-imperialist positions, can, thanks to his notoriety, spy the entourage without arousing suspicion. During a ceremony in Angkor, he is surprised to see at the same table a colonel from CIA, a south Vietnamese Captain and the diplomat who is accompanying the ambassador. The three men, who are in connivance, are stocking ammunitions for the coup in the temple of Bayon. But on the D-DAY, few hours before the arrival of the American and Vietnamese soldiers, the Royal Khmer Army forces stopped the renegades. The ambassador, feeling bad for having participated indirectly to the failed coup, comes back to her country.
