Clan (2012)

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.
