Ten volunteers enter an experimental post-catastrophe world to see if they can survive and rebuild after a global disaster. Cordoned off in a downtown Los Angeles warehouse, they must secure shelter, filter water, and defend their new home from thieves.

With their power supply dwindling, the volunteers attempt to build a generator that runs on smoke from wood scraps. When they scavenge the nearby streets for supplies, they must face off with a motorcycle-riding thug.

After securing the basic necessities for survival, the volunteers focus on the one creature comfort they can't live without: a hot shower. But focusing on comfort leaves them open to a massive attack that threatens their long-term survival.

After an attack shatters the volunteers' sense of security, they must focus on building weapons and fortifying the warehouse. But before they can finish, a truckload of gun-toting traders arrives to test the volunteers' unity.

The volunteers have the opportunity to up their electricity and power capabilities when they scavenge a stock of abandoned solar panels. But the experiment takes a violent turn when a stranger breeches their security and tries to steal their supplies.

The volunteers are rocked by the disappearance of a treasured member during a search party mission. The loss spurs them to build a collection of communication devices in hopes that their missing member is somewhere out there…listening.

The Colonists run into missionaries on a river trip, and John V's moral compass is shaken. The arrival of two new visitors creates an internal rift and the group must sacrifice one of their own to survive.

A kidney stone puts Joey down for the count, and while he recovers, the Colonists are surprised by a new arrival and a very wet situation. Mike and Vlad set out on what turns into a dangerous recon mission.

The colonists work on a scout vehicle and make some customized changes on their escape truck. Tempers flare when the traders return. A colonist hits his breaking point.
