Detroit built its identity on the auto industry, and Fault Lines arrives as that industry's decline drags the city down with it. The film walks through neighborhoods hollowed out by plant closures and layoffs, talking to autoworkers who once had stable union jobs and now face foreclosure, unemployment, and shrinking city services. Interviews with residents, labor organizers, and local officials trace how the downturn in manufacturing rippled into schools, housing, and city budgets, turning a company town's crisis into a municipal one. The crew shoots abandoned factories and emptied-out blocks alongside the neighborhoods still hanging on, letting the physical decay make the economic argument as much as the interviews do. Rather than treating Detroit as a symbol, the film stays close to the people living through the collapse: workers weighing whether to leave the city, families adjusting to reduced incomes, and officials trying to explain what recovery might even look like. It is a ground-level account of what happens to a city when its core industry falters.
