In the Bay Area, the San Francisco Rapid Response Network, along with sister networks across California, serves as the front line of the local fight against the current wave of federal immigration mandates. The network, the first of its kind in the country, maintains a 24-hour hotline where residents, hoping for quick legal support, can call to report suspected Immigration and Customs Enforcement (ICE) presence in their neighborhood. Unexpectedly, the hotline’s volunteers have become stewards for a confused and scared population, desperate to find answers amid chaos. Using real phone calls, "Enforcement Hours" explores this abstract, faceless world. Anonymous callers, their intentions unknown, punctuate unpredictable movements across San Francisco.
