Calumet City

Patti Black is the most decorated cop in Chicago; a ghetto street
officer, she redefines the word badass. But the steel-plated exterior
she shows to the world - solitary, friendless, loveless - hides the
hideous traumas of her past. As an orphaned child, she was horribly
sexually abused by her foster parents, and the torments of the past are
only barely contained by her meticulously maintained tough-guy persona.
When a serious of seemingly unrelated cases - a drug bust gone bad, a
mayoral assassination attempt, the abduction and murder of a states
attorney, a long-hidden body walled up in a tenement basement - all
point in her direction, she comes to the horrified realization that her
past is no longer staying in its deeply suppressed place. It's back and
it's hunting her down.
