Loosely based on the life of director Juan Antonio de la Riva, VIDAS ERRANTES tells the story of aging Francisco and his young assistant Guillermo, two men bound together by their unadulterated love of the cinema. Living in a small town, the two men project their films, which are often the only form of entertainment for the townspeople. They also travel from town to town, showing the films for money. When they finally make enough profit, Francisco and Guillermo build their own cinema, but unbeknownst to them, their actions will trigger a series of unexpected events. de la Riva`s film, a sort of Mexican CINEMA PARADISO, pulsates with a true love of film.
