Doomsday Preppers Season 3, Episode 2: The Gates Of Hell

Don't Betray The Colony

Some preppers believe in safety in numbers -- as is the case for Jeff Mann, who leads "the Colony," a community of 25 preppers unified with the single purpose of surviving doomsday. Watch as he prepares his son, Colten, to take the reins by having him hunt down live boar in the Florida swamps and builds the Colony's very own gallows -- an important message that there are laws to be upheld, even in times of chaos.

Whatever It Takes

Could an explosion on the surface of the sun cause mayhem on Earth? Jason and Jacob are a father-son team from Alabama who are prepping for exactly that: a global solar flare with the potential to wipe out power grids around the world. Jason was almost stranded for good in the wilderness when he was 19, but that will not stop him from prepping in those very same woods by molding his own ammunition and preparing his 20-piece bug-out pack.

People Become Animals

The possibility of World War III is a major concern for many preppers, including former Marine Alex Dunbar, who is training a private army of German Shepherd attack dogs in San Luis, Colorado. In the woods of East Appalachia, Brenda McSwigan fears that a vicious mutating virus will lead to a pandemic that will overwhelm hospitals and leave the rest of the country in chaos. Another prepper, Grace McLeod, secures her 3,500 square-foot fortress before an economic collapse.

Take Our Country Back

Deep in Oregon's backcountry sits an 80-acre off-the-grid estate that prepper Curt and his family have designed as a fortress in the event of an economic collapse. Isolation is one of their greatest strengths, but the protective measures are endless: a 3,000-square-foot greenhouse, a lake with 1 million gallons of water, infrared cameras and a high-tech software system — not to mention the children are trained in marksmanship.

The Fight Ahead

At his home in Arizona, he is working on executing the biggest prep of his life — a 140-foot-long escape tunnel from his family's house to a bug-out vehicle. With the help of his wife and daughter, he begins construction — but as the project unfolds, they realize they're in over their heads.

We Are The Marauders

While many preppers believe defense is the best strategy for surviving a Doomsday scenario, one family in Tacoma, Wash., is banking on a good offense. Tyler, his wife and his cousin have assembled a group of like-minded, would-be marauders from their neighborhood in preparation for a catastrophic domestic terrorist attack. They have only six months' worth of food because they plan on taking what they need in order to survive — and to stay safe, they're developing the ultimate suit of armor.

Total Destruction

A devastating EF-5 tornado, like the one that struck Oklahoma in May of this year, can throw buildings into the air and hurt hundreds of people. In Tennessee, Tracy is preparing for just that. Tracy has spent six years prepping his farm for a super tornado, but if it does hit, he doesn't plan on hunkering down — he plans on gathering his family and making a getaway in his mobile safe room.

No Stranger To Strangers

Outside of Fort Worth, Texas, Vietnam veteran Richard Huggins is preparing for a nuclear strike by a terrorist state, a concern he believes is amplified by his proximity to the defense production hub of Dallas-Fort Worth.

Nobody Will Be Ready

Meet two Tennessee families who are both preparing for an earthquake in the New Madrid Seismic Zone. David Mays believes all roads and bridges leading out of his neighborhood will be destroyed, so he's devising the ultimate Doomsday drone fleet.
