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.

Set in Toronto at the dawn of the 20th century, Murdoch Mysteries is a one-hour drama series that explores the intriguing world of William Murdoch, a methodical and dashing detective who pioneers innovative forensic techniques to solve some of the city's most gruesome murders. Murdoch's colleagues include the love of his life, coroner and psychiatrist Dr. Julia Ogden, a staunch ally who shares the detective's fascination for science; Constable George Crabtree, Murdoch's eager but sometimes naïve right-hand man; Inspector Brackenreid, Murdoch's skeptical yet reluctantly supportive boss; and coroner Dr. Emily Grace, Dr. Ogden's protégé.

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.
