The film examines the contribution of motor vehicles to atmospheric pollution, with a focus on Los Angeles, where topographical and climatic conditions produce photochemical smog, and a deeply car-dependent society adds enormous quantities of vehicle exhaust to the mix. The effects on human health are shown; experiments with animals and human volunteers are explained and the adverse effect upon plant life demonstrated. An estimation of the cost in economic and human terms is provided for California and the US as a whole. The film shows tests of vehicle engines both to examine the emission of unburnt hydrocarbons and to demonstrate methods of control in the crankcase and the exhaust.
