Thirteen-year-old Bastien is the center of a reconstructed family: six half-brothers and sisters, eight "parents," and as many houses. His tasks within the family are far more complex than what he has to do at school. But enough's enough: the children decide to wage a revolution and turn the rules upside down. All together, they squat a large apartment and now it'll be up to the parents to come to them!
Aurora's life suddenly gets complicated after her seven grandkids arrive to her house for vacation.

When her grandkids hear her mention a mysterious man named "Gerry", they put all seven of their heads together to figure out who he is: Aurore's first and only true love who just might turn out to be their long-lost grandfather, too! Hoping to trigger old memories that could snap her out of her amnesia, they join forces to sneak Aurore out of the nursing home and set out into the wilderness on a mission to find the legendary "Grandpa Gerry". But the adventure turns out to be a lot more than they bargained for!
