 Panic in Year Zero! (1962)

While on a fishing trip, Harry Baldwin (Ray Milland) and his family 

hear an explosion and realize that Los Angeles has been leveled by a 

nuclear attack. Looters and killers are everywhere. Escaping to the 

hills with his family, he sets about the business of surviving in a 

world where, he knows, the old ideals of humanity will be first 

casualties. Not one to give up, he holds up a store for supplies and 

hides the family in a cave.

One the the first acts by our hero after the nuke goes off is to rob a hardware store
 at gun point , for weapons because uh maybe those not as ethical as our hero might do
something like uh maybe rob at gun point.
