I Soliti Idioti return to the cinema ten years after the second film and many things have changed in the world. We will see the most beloved characters compete with the contemporary, with the same cynical and amused eye that distinguished the previous episodes. This new adventure focuses on a current and universal theme: the family.
Giacomo, the main character, 35 years of laziness, is a man who doesn't know and doesn't want to fight. He is a introvert curmudgeon, a little bit nerd but not very social, who walks with the look downward on his device without giving to the people what they would like from him: only a little bit of attention and enthusiasm. He loses his job, he is left by his wife and coincidentally he remains closed in the women's bathroom of the art-house cinema, together with the owner's small dog.
Lorenzo conocido como Ghandi y Elena se conocieron a los 18 años durante unas vacaciones por Nevada y terminaron haciendo la clásica locura: se casaron en Las Vegas. Unas horas más tarde, todos iban por su propio camino, dejando atrás el incidente (o al menos eso es lo que piensa Elena). Veinte años después Elena está a punto de casarse con un hombre muy rico y brillante, pero su mejor amiga Sara, una abogada, le informa que, estando técnicamente todavía casada con Lorenzo, primero debe disolver ese vínculo o será acusada de bigamia. Por lo tanto, Elena y Lorenzo deben regresar a Las Vegas y obtener una sentencia de divorcio en unos días. Si realmente quieren.
