A crazed woman attempts to steal a mother's unborn infant from the womb; a massive grizzly bear attacks a researcher; an ex-Marine shoots a woman.

While on a first date, a young couple is taken to a deserted reservoir and shot execution-style; a 13-year-old girl escapes from the men who have abducted her.

A train derails near a farmhouse and blankets the home's residents in poisonous gas; a woman is left for dead after she is run off the road and attacked.

Two of the pod bosses in the Clark County Jail begin to spark chaos as they make threats against three of the participants' safety.

The civilian participants are forced to deal with the stresses of being incarcerated; two of the participants believe that they can't handle it much longer.

The six participants find themselves at turning points; Ashleigh has a life-changing epiphany; Quintin and Sheri have conflicting feelings while under cover.

The men face a different set of challenges after they switch pods, and the women develop suspicions that someone may turn out to be a snitch.

As Quintin sleeps in a cell of the Clark County Jail along with numbers of other inmates, raw sewage begins to flood geyser-style out of C-Pod's floor drain.
