A thriller about a quarantined town where anyone over the age of 22 has succumbed to a mysterious virus begins with those left alive scrambling to survive.

The remaining residents of Pretty Lake collect the dead in hopes that the quarantine will be lifted once the bodies are burned.

The power goes out across Pretty Lake, and tensions escalate as communications are cut off with the outside world.

A young teacher fears that she may succumb to the virus; Chuck institutes a harsh and public punishment for a kid caught stealing; and Adam's search for the truth continues.

The residents of Pretty Lake remain cut off from the outside world, but on the bright side, at least their power has been restored.

The government arrives in Pretty Lake with a cure for the virus; at the same time, Adam reveals information that could save his friends.

Adam and Wiley try to escape Pretty Lake using the route laid out by Adam's father. Meanwhile, Chuck and Harrison engineer an escape plan, and Gord realizes that the orphanage is dangerously low on food.

Liam identifies himself as a scientist who can possibly provide the survivors with a cure, but Adam isn't convinced. Meanwhile, Renee returns Ronnie's gun and convinces him to help find her brother, while Chuck and Harrison deal with the repercussions of their escape attempt.

Ronnie takes Eric's body to his sister and discovers that she leads a group of survivalists. Meanwhile, Stacey takes drastic steps when Mark threatens to leave, and Wiley turns to the Mennonites for help when she realizes that she can't feed Jason.

Frances and Harrison go to the compound to get revenge on Renee, unaware that Mark is intending to do the same thing. Meanwhile, Ronnie and Lamar stage a coup, and Liam and Wiley hunt for a survivor turning 22 so that they can test the cure.

While Adam tries to use Liam's files to force Horatio and the government to release the Pretty Lake survivors, Wiley goes to the Horde compound to try and get the cure back from Renee.

Wiley and Mark manage to get the cure from Renee with Ronnie's help. Meanwhile, Adam puts his life on the line negotiating an extraction with Horatio.
