Episode 4

Eighteen to twenty castaways will compete against each other on Survivor. All castaways will compete to outwit, outplay, outlast and ultimately be crowned Sole Survivor.

In the criminal justice system, the people are represented by two separate, yet equally important, groups: the police, who investigate crime; and the district attorneys, who prosecute the offenders. These are their stories.

Mark Scout leads a team at Lumon Industries, whose employees have undergone a severance procedure, which surgically divides their memories between their work and personal lives. This daring experiment in "work-life balance" is called into question as Mark finds himself at the center of an unraveling mystery that will force him to confront the true nature of his work… and of himself.

The most miserable person on Earth must save the world from happiness.

An emotional thrill ride through the day-to-day chaos of the city's newest state-of-the-art trauma center and into the lives of the courageous doctors, nurses and staff who hold it all together. This is one of those days.
