The Last Alaskans - Season 4

District 21 of the Chicago Police Department is made up of two distinctly different groups. There are the uniformed cops who patrol the beat and go head to head with the city's street crimes. And there's the Intelligence Unit, the team that combats the city's major offenses - organized crime, drug trafficking, high profile murders and beyond. These are their stories.

No job is more stressful, dangerous or exhilarating than those of the Firefighters, Rescue Squad and Paramedics of Chicago Firehouse 51. These are the courageous men and women who forge headfirst into danger when everyone else is running the other way and whose actions make the difference between life and death. These are their stories.

High Potential follows Morgan, a single mom with an exceptional mind, whose unconventional knack for solving crimes leads to an unusual and unstoppable partnership with a by-the-book seasoned detective.

9-1-1 is a fast-paced exploration into the lives and careers of first responders – cops, paramedics, firefighters – the people who put their lives on the line to save others.

Each edition of FBI True focuses on dynamic insider conversations between agents when they meet at the FBI's favorite bar, the Arts & Crafts Beer Parlor, just down the block from their New York headquarters. It's a hallowed place where law enforcement colleagues talk frankly about the triumphs, tragedies and real truths of their jobs. In this relaxed setting, they share hair-raising stories of dangerous missions carried out by the FBI in the United States and worldwide. With everything on the line, what choices did they make? How did they keep their cool with a kidnapped child's life on the line, or with a bomb ticking in an unknown location, or a terrorist on the loose?

FBI True features never-before-seen surveillance video, interrogations with hostage takers and terrorists, and personal photos from the agents' collections. This is the FBI like you've never seen, as agents disclose what happened, and how they felt while working on some of the biggest and most compelling crimes of our time, revealing their fears and exulting in their victories. Viewers will get a spine-tingling look inside the manhunt for a bomber responsible for injuring 30 people in Manhattan; the desperate search to find Hannah Anderson, a high school cheerleader kidnapped in California; the command center at Waco as agents helplessly watched women and children consumed by fire as the David Koresh's cult compound ignited; the complex search for the Beltway snipers in Washington, DC; the frustrating effort to find the terrorists who attacked the U.S. mission in Benghazi killing the ambassador; and the search for the brutal Boston mob leader Whitey Bulger.
