Former undertaker and ex-police officer Luc Conrad comes back to Switzerland to attend a birthday party in a hotel. When the hotel manager dies under mysterious circumstances, he secretly begins to investigate whether it was a murder.

A detective leaves the force to take over the family business as an undertaker at the same time as he is being investigated for murder. His close encounters with corpses and his earlier police training lead him to see things some of his ex-colleagues miss and he investigates the crimes he encounters in an unofficial capacity often to the dismay of the official police.
