59-year-old Isidro Hernández (Carlos Iglesias) is unemployed, having gone two years without receiving any job offers, as no one seems interested in hiring anyone over 50-years old. So, he decides the only way to get back to work and feel useful again is to start his own business. But in a globalised world where youth and technology reign supreme, what can he undertake when society relegates those his age to the role of caring for their grandchildren? The answer is clear: with the help of Arturo (Roberto Álvarez), a successful writer of romantic novels, and Desiderio (Ramón Barea, Rosa’s Wedding SPA21), a retiree who wants to be a grandfather, they will embark on an ambitious project: setting up a kindergarten. To develop it, the three friends enter a coworking space, full of young people, where they will have to bring out the entrepreneur within them to get their venture off the ground. A crowd-pleasing and affectionate comedy about modern working environments from debut director Santiago Requejo, Grandfathers proves that one is never too old to start something new.
