A police shootout leaves four thieves dead during an explosive armed robbery attempt in Chicago. Their widows have nothing in common except a debt left behind by their spouses' criminal activities. Hoping to forge a future on their own terms, they join forces to pull off a heist.

A riveting police drama about the men and women of the Chicago Police Department's District 21 who put it all on the line to serve and protect their community. District 21 is made up of two distinctly different groups: the uniformed cops who patrol the beat and go head-to-head with the city's street crimes and the Intelligence Unit that combats the city's major offenses - organized crime, drug trafficking, high profile murders and beyond.
