Christian de Kersaint-Gilly was shot twice in the chest on his estate in Brittany. Dispatched to the scene of the tragedy, Captain Marleau came to suspect the wife of the deceased, Joséphine de Kersaint-Gilly. Indeed, Christian had just sold part of their property to two ambitious men: Étienne Quemener and his partner, Vincent Salmon. Both intend to transform the small, highly picturesque fishing town into a luxury marina. This ultra-modern place is supposed to attract a hand-picked clientele, to make it a fashionable holiday resort. (thetvdb.com)
