History is Ours narrates the struggle of the workers of the Refrescos Pascual soft-drink company against its owner, Rafael Jiménez, the official trade unionism of the CTM and the labor authorities of the governments of José López Portillo and Miguel de la Madrid, between 1982 and 1985. It documents the workers' difficult struggle to take over the company, when justice, which had been elusive, finally proved them right, and opened the possibility that these brave, tenacious workers would become collective owners of the company. Today, these soft-drink fighters resist a system that hits Mexican companies in favor of the monopolistic transnationals. The film is an account of one of the most brilliant episodes of the contemporary Mexican labor movement, an example of unity and class consciousness, embodied by men and women who make their struggle a tribute to comrades Concepción Jacobo García and Alvaro Hernández García, tragically fallen at the beginning of this historic event.

Basada en un valioso registro fílmico de aquel movimiento, La Historia es Nuestra da cuenta también del difícil proceso de adjudicación de dicha empresa a los trabajadores, cuando la justicia, que les había sido Indiferente y adversa, por fin les daba la razón, y abría la posibilidad de que aquel grupo de trabajadores valientes y tenaces crearan una cooperativa y se convirtieran en propietarios colectivos de esa empresa. Hoy, los luchadores de refrescos Pascual resisten a un sistema que golpea a las empresas mexicanas en favor de los intereses monopólicos de las trasnacionales.
