Desc: Granny Boom: Directed by Christiane Lehérissey. With Fanny Cottençon, Didier Bezace, Claire Maurier, Michel Robin. A couple of active 50 year olds thought they were done taking care of their two now adult children. The new stability they thought they had found will be disturbed by one's new child and the other's over-reliance on them for babysitting.
