The messages the government was trying to send in the film "Duck and Cover" were: 
- surviving the atomic bomb
 - surviving the atomic bomb attack depends in being prepared and knowing what to do. 
 
The phrase "duck and cover" meant putting one's self into duck position and covering. The idea behind the saying was that if one "ducked and covered", one would be able to survive an atomic bomb. It was released in 1952 during the Cold War, when there were threats that the Soviet Union would drop an atomic bomb on American territory.
