When two women detectives in the CID division of a large city police force, one a forty-year veteran, the other a rookie, are forcibly teamed together in an unfriendly partnership, the rookie follows the many-years-old cold case of a painting found in a stolen deposit box. As she traces its path from obscurity to potential world fame at auction, the older detective, disdaining the efforts of her younger partner, investigates the more recent and seemingly unrelated violent homicide of an important city councilman. The paths of both widely different investigations merge, however, united by evidence in the cold case, and the two detectives become as one to successfully hunt down those guilty of the homicide.
