The same day, 480 miles apart, two cops are handed two unusual investigations. Niémans, a man experienced in and possessing an infallible instinct when it comes to criminal matters, but who masks painful, obsessive fears, heads for Guernon, a university town in the Alps, where a grisly murder has taken place. Max Kerkérian, young, sharp, solitary, a former car thief who joined the police force because of his love night and danger, is carrying out an investigation at Sarzac into the desecration of the tomb of a child who died in 1982. Soon, both investigations will link up.
