We talk post-apocalypse from the 1980's.

From IMDB: After a nuclear war, Phillip Hammer and Marlowe Chandler have spent fifteen years on their own in a bunker, stuffed with junk from the 40s and old detective novels. Now, nineteen-years-old, they leave their shelter to find a world full of mutants, freaks, and cannibals. They become famous detectives in the struggle for the two keys that could fire the last nuclear weapon.
