Los Angeles sits on a network of active faults, and this film uses that fact as its spine, anchored by never-before-seen footage from the Northridge earthquake of January 17, 1994. The quake hit at 4:31 in the morning, measured 6.7, and killed 57 people while injuring roughly 8,700 more, with damage estimated near $20 billion across the San Fernando Valley. Archival footage shows freeway overpasses collapsed, apartment buildings pancaked, and residents pulled from rubble by first responders working through the night. The film follows those rescue efforts alongside interviews describing the psychological aftermath, including post-traumatic stress among survivors who lived through the shaking. It then widens out from Northridge to the broader seismic hazard facing Southern California, covering the geology that produces these events and the building codes and warning systems developed in response. The Northridge footage carries the film; it is blunt, unpolished, and close enough to the event to still feel urgent.
