In 1973, Philadelphia’s Chinatown was threatened by a proposed freeway ramp that would have choked off the neighborhood from the rest of the city. A contingent of spiritual leaders, community organizations, youth and elders successfully organized a campaign to save Chinatown from destruction. Pioneering filmmaker Jon Wing Lum followed the successful campaign using his groundbreaking style of catalytic cinema in which the role of the film is not only to witness, but also to be an agent of change.
