NOVA - Season 28

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.

A darkly gripping series, The Mortician chronicles a trusted family-owned funeral home that hid behind a façade of decency and propriety to take advantage of loved ones at their most vulnerable moments. In the early 1980s, David Sconce, scion of the Lamb family, took over the family business and sought to exploit the deceased in numerous ways to expand their earnings. Driven by profit, the Lamb Funeral Home in Pasadena, California engaged in years of morally questionable and inhumane practices.
