A filmmaker travels by herself into the Midwest to meet the American men who have chosen to live in decommissioned military bunkers and nuclear missile silos, also known as “preppers.” Meanwhile, she also follows the process of building and selling these structures to the wealthy and not-so-wealthy.

Interviewing her subjects without judgment, Jenny Perlin burrows deep into the lives of men making homes in elaborate underground structures. As they prepare for supposed impending nuclear fallout, this documentary provides an intriguing study of loneliness and American masculinity in crisis.
