In the history of Hollywood there are few films with a story behind its making as dramatically riveting as that of Salt of the Earth. Made during the height of the McCarthy era by a group of blacklisted filmmakers who were among the best and the brightest Hollywood talent of the day, Salt of the Earth is itself a powerful and emotionally charged feature length film. For the first time, this film tells the true story of this troubled production, while also allowing the user to meet the filmmakers, understand the historical background and view the film, all on the same platform.

Salt of the Earth is based on a 1950 strike by zinc miners in Silver City, New Mexico. Against a backdrop of social injustice, a riveting family drama is played out by the characters of Ramon and Esperanza Quintero, a Mexican-American miner and his wife. In the course of the strike, Ramon and Esperanza find their roles reversed: an injunction against the male strikers moves the women to take over the picket line, leaving the men to domestic duties. The women evolve from men's subordinates into their allies and equals.
