Murders in... is a collection of French-Belgian police TV movies taking place each time in a different French city and region.

As the end of the world is announced, Akim, Julie and Kevin begin to achieve everything they have always wanted to do, but after the world does not end, the world wakes up with a terrible hangover.

The body of a real estate developer and candidate for mayor of Bordeaux is found murdered in his home according to a ritual reserved, two centuries earlier, for runaway black slaves. Discovered by his closest friends, all, like the victim, from prominent Bordeaux families with a troubled past during the slave trade. On the spot, Clémence Lacoste, a police captain accustomed to the field and a native Bordelais, is forced to team up with Lieutenant Antoine Rosy, an elegant Parisian more accustomed to the office than the field... To find the killer and stop this series of murders, our two heroes are going to uncover buried elements of Bordeaux's history... but above all of their own past and origins.
