"Razón de Ser: Luis C. Garza" is a documentary that chronicles the story of this rare Chicano photographer who uniquely documented activist movements on both coasts, and internationally, during the 1960s and 1970s.

Perhaps best known recently for his work in co-curating the blockbuster LA RAZA exhibition at The Autry as part of The Getty's Pacific Standard Time: LA/LA, Garza's work spans from the Chicano civil rights movement in Southern California to New York where he captured scenes of his South Bronx neighborhood, demonstrations on women's rights, and rallies by the Young Lords Party who sought to empower Puerto Ricans and other colonized people. It also includes his 1971 travels to Eastern Europe for the World Peace Conference where, as a young Chicano student, he met renowned Mexican muralist David Alfaro Siqueiros.

Currently, 80-year-old Garza is seeking an institution to properly archive his nearly 8,000 film negatives of his life's work.
