Panic in Year Zero!
Harry Baldwin (Ray Milland), his wife Ann (Jean Hagen), their son Rick (Frankie Avalon), and daughter Karen (Mary Mitchell) leave suburban Los Angeles on a camping trip. The Baldwins notice unusually bright light flashes coming from a great distance. Sporadic news reports broadcast on CONELRAD hint at the start of an atomic war, later confirmed when the Baldwins see a large mushroom cloud over what was Los Angeles.
The family initially attempts to return to rescue Ann's mother, who lives near Los Angeles, but soon abandons these plans as panicked refugees climb over one another to escape the fallout from multiple nuclear explosions. Witnessing the threads of society being torn apart, Harry decides the family must find refuge at their secluded vacation spot.
Along the way, they stop to buy supplies, or, in the case of hardware store owner Ed Johnson (Richard Garland), take them by force when he won't accept a check. They also encounter three threatening young hoodlums, Carl (Richard Bakalyan), Mickey (Rex Holman), and Andy (Neil Nephew), on the road, but manage to drive them off.
After a harrowing journey, the Baldwins reach their destination and find shelter in a cave, while they wait for order to be restored. They find that Johnson and his wife are their neighbors, but not for long. The three thugs appear and shoot them. A farming couple suffers the same fate, and their teenage daughter, Marilyn (Joan Freeman), is kept as a sex slave. Karen is also raped when Mickey and Andy happen upon her. With guns in hand, the Baldwin men fight back, killing the two murderers and freeing Marilyn. Marilyn returns with them back to camp. Some time later Rick is out with Marilyn chopping wood. Carl sneaks up behind Marilyn and forces her to drop the rifle she is holding, and begins to question her about what happened to his friends. Rick tells him to back off and throws a piece of wood at him while at the same time Marilyn breaks away and grabs the rifle and shoots Carl dead, but at the same time Carl fires a shot off hitting Rick in the leg.
With Marilyn's help, they get the young man to Doctor Strong (Willis Bouchey). The doctor does what he can, but the boy needs a blood transfusion and must be taken to an army hospital more than a 100 miles (160 km) away, or he will die. On their drive there, they encounter a military patrol scouting for the army that is reestablishing order. After a tense meeting, the group is allowed to continue. Watching them depart, the soldiers note that they're among the "good ones" who escaped radiation sickness by being in the mountains when the bombs exploded. As the family drives on, a closing title card states: "There must be no end – only a new beginning".
