影片讲述了美国著名的社会活动家凯萨·查维斯(Cesar E Chavez)的生平故事。他是墨西哥裔的美国劳工运动者,联合农场工人联盟的领袖。二十世纪时,他为了给农场季节工人(migrant farm workers:为找工作四处迁徙的人)争取更好的权利和公平的工资而四处奔走,最终取得了全国人民的同情与支持。导演迭戈·鲁纳表示,不仅在农场工人的世界里,在世界各地还有很多人需要像查韦兹一样的伟人来帮助他们。他希望通过这部电影能唤起更多人关注美国移民改革的问题,以及一些国家的许多无代表社区。对于迭戈·鲁纳来说,电影就是一种改编世界的工具,它正在发生,无处不在。Chronicling the birth of a modern American movement, Cesar Chavez tells the story of the famed civil rights leader and labor organizer torn between his duties as a husband and father and his commitment to securing a living wage for farm workers. Passionate but soft-spoken, Chavez embraced non-violence as he battled greed and prejudice in his struggle to bring dignity to people. Chavez inspired millions of Americans from all walks of life who never worked on a farm to fight for social justice. His triumphant journey is a remarkable testament to the power of one individual's ability to change the world.
