Carefree and childless, Pio and Anais have planned the perfect "grown-up" wedding: Italy, the sea, dancing until morning. The only rule is no children. But their friends - family and burdened with offspring - are faced with a dilemma: there is no one to leave the children with, and it is unthinkable to miss the celebration. The only way out is to secretly bring the children, hiding them from the newlyweds. Parental conspiracy turns into a family madness with cake in their hair and children's squealing instead of fireworks, but contrary to expectations, will make the holiday times more fun.
