August 1715. After going for a walk, Louis XIV feels a pain in his leg. The next days, the king keeps fulfilling his duties and obligations, but his sleep is troubled and he has a serious fever. He barely eats and weakens increasingly. This is the start of the slow agony of the greatest king of France, surrounded by his relatives and doctors.

Michel Piccoli plays a police inspector whose best friend is murdered on the orders of gang boss Charles Vanel. The inspector knows full well that Vanel is too crafty and well-connected to ever stand trial for his crime, so he carefully lays a subtle trap for his adversary. Unfortunately, both Piccoli and Vanel are thwarted by a pair of scheming females.
