MEET PHILLIP AND MARLOWE, THE POST-NUCLEAR PRIVATE EYES.
Fifteen years after a nuclear holocaust has turned the earth into a world full of mutants, freaks and cannibals, two young men emerge from the bomb shelter where they have been living. Everything they know about the world, they learned in the shelter, which was stocked with 1940s food rations, clothing and Raymond Chandler detective novels.
This has never been released to DVD or blu-ray and it isn't officially available on streaming services. That being said, someone did upload a VHS rip to YouTube. :)
