In the new NBC drama, Jennifer Lopez stars as “sexy New York detective (and single mother) Harlee Santos, who fell in with a tight-knit group of dirty cops, taking bribes and protection money that she uses to provide the best life for her honest and talented daughter. When she’s trapped by the FBI, however, and forced to inform on her own “brothers,” she’ll have to walk the fine line between love, loyalty, honor and betrayal, and try to keep it together for her daughter’s future.”

The legendary Ray Liotta and Drea De Matteo (“Sons of Anarchy“) also star in the new series slated to premiere on Thursday, January 7 at 10/9c.
