The funniest family in Spanish cinema is back accompanied by a surprise visit: the mother-in-law. Santiago Segura (the father), Toni Acosta (the mother), the children Martina D'Antiochia, Calma Segura, Luna Fulgencio, Carlos G. Morollon and Sirena Segura and the brothers-in-law played by Leo Harlem and Silvia Abril will live a new and fun adventure in which, again, many Spanish families will be reflected.
