Nothing abnormal when Clément Royan is called on a murder case. But it takes a completely different turn when the man found turns out to be a former employee of the Casino managed by his grandmother, Denise Royan. Clément will then have to reconnect with his family who made their fortune in the casinos, but from whom he moved away when he chose his police career to the detriment of the family business. Juggling between old Norman traditions and family secrets, Captain Royan will also have to collaborate with a former colleague for whom his feelings do not seem to be completely gone. Clément will have no choice but to keep his cool to solve this mystery that hovers over the Normandy coast.
