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.

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.

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.

Mike recovers from a nasty crash and helps the others beef up the Colony's defenses. Then, the Colonists race to finish the escape truck before the marauders launch their final offensive.

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.

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.

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.
