Four sisters conspire to kill their obnoxious brother-in-law but murder isn't easy especially when they have to contend with bad luck, the victim's senile mother and a pair of bumbling insurance investigators who can't afford to pay out.
Clan draws you into the lives of the Goethals sisters, tied together by the premature death of their parents, they've clung to each other like a real clan. But ever since their fifth sister's marriage the bond has frayed. Together, the four of them plot the murder of their brother-in-law, Jean-Claude, a pain in the ass just asking to be liquidated. Clever and quick-witted, the sisters devise a whole host of ingenious schemes. But while planning a murder is easy, committing it is another story... and with each mounting failure, the collateral damage grows.—Caviar
