In Quebec, four senior citizens (Olympia Dukakis, Jan Rubes, Jean Lapointe and Cloris Leachman) meet for the first time at the funeral of a mutual friend and discover that the deceased had been cheated through a retirement home scam. To avenge their peer and set matters straight, they embark on a complex caper involving spying, burglary, disguises and a little old-fashioned sleuthing. Along the way, they may even find some romance.
