Panic In Year Zero (1962). An American family goes on a camping trip the day LA is struck by a Soviet nuke. When they hear the emergency alert over the radio, the father diverts to a few small rural towns to go shopping to buy and stockup on basic essentials before all the panic sets in. The family then has to survive while the country is placed under martial law, as looting, rape and killing begins. The marauders are exploiting the crisis on the take, juvenile delinquents are robbing homes and abusing women and children, the mass exodus of people fleeing the cities is causing chaos, supply shortages and traffic jams. The family has to get out of dodge and fend for themselves to survive as the US military takes law enforcement into their own hands.
