Apocalypse 101

Meet four former Marines who believe that they have what it takes to survive any doomsday scenario. Joel, Mark, Mike and Jimmy own Forge Survival Supply; their mission, use what they have on hand to teach and test their clients' skills. In a remote area of Colorado, Mike and Mark meet a couple who are serious preppers. They want to step up their game, but the guys worry their open land and young children could interfere. The Marines will put them to the ultimate test with a simulation attack.

No matter what happens, these former Marines are ready to survive. Joel, Mark and Mike use what they have on hand to teach and test their clients' survival skills. At the shop, young gunsmith Tommy wants to learn about other weapons he could use to survive. With Jimmy's knowledge and survival skills, Tommy will be able to take his prepping to the next level. Later, Joel and Mike head to the home of a Vietnam vet who wants to retrofit his house to bug in.

Owners Mark and Jimmy head to New York to meet Jay and Daniel for a consultation to test their survival skills. Jay and Daniel are worried about how to get out of New York in an emergency, and rightfully so. With 8.2 million inhabitants and only a few ways in and out, an emergency situation in the Big Apple is no picnic. Back at the survival store in Colorado, Joel and Mike meet Theo, a prepper who's worried about nature wreaking havoc on Earth.

Former Marines Mark and Mike get a client at their survival skills company, Forge Survival Supply, like none they've met before. Jeffrey is a mountain man, who camps year round and lives out of his truck. He's worried about security, so the guys devise some custom preps to keep him safe in the wilderness. Later, Leianna, a mother of seven, comes in to get some advice on buying a bunker to protect her family but the guys are worried that her small children will not hold up well in a bunker.

At the survivalist store, two preppers fear a nuclear attack and are worried about providing for their families. They plan to mine for gold if money loses value and give Joel and Jimmy a lesson in prospecting. Meanwhile, Mike and Mark head out to Texas, where they've been hired by Rick, who as a child was evacuated from Vietnam and fears another catastrophic scenario. They soon find out that Rick isn't your average prepper: he has a weapons room that could supply a small army.
