What saves a love life? For François, the answer is simple: kill all cats!

One day, François has a revelation: what if he's single because of... cats? What if cats are the reason men can't manage to build lasting relationships with women?
The minute a couple has a fight, the woman always rushes home and snuggles up with her cat. François even has a name for this aberrant behavior: felinism! To save society from this plague, what better plan than to go out at night and eliminate these pests from the neighborhood?
But one thing he didn't count on was Topaze, a.k.a. Igor, a Russian cat who can talk and seems happy to help François wipe out his own species... at least at first!
