Jennifer is an Assistant District Attorney for the State of New York, New York County. A beautiful, inexperienced, criminal defense attorney, she foils a plot by Michael Moretti, the rising star of one of the most powerful organized crime families in America. Manhattan District Attorney Robert Di Silva, believing that Jennifer is truly responsible, fires her and vows to destroy her for her part in the fiasco with Michael Moretti.

Di Silva arranges for the young lawyer Adam Warner to meet Parker in an attempt to persuade him that she is truly responsible for the bribe. Upon meeting her Adam falls for Jennifer and realizes that she isn't guilty at all. With Adam's help Jennifer begins to rise again, meanwhile Moretti, inspired by her determination to succeed, decides he would like to induct her as the Family consigliere (a mafia lawyer).

Adam Warner, despite being married and groomed for the United States Senate, and with the possibility of a White House destination, can not help falling in love with Jennifer. When Adam tells Jennifer that his wife has asked for a divorce, Jennifer meets with Warner's wife, Mary Beth. Being so close to the Senate election, the two women decide it is best for Adam to wait until after the election. Mary Beth however sleeps with Adam one last time, in the process tricking him into impregnating her. Adam learns that his wife is pregnant, wins the election, and tells Jennifer that he truly loves her but they must end their affair. Jennifer having previously discovered that she too is pregnant and not wanting to hurt Adam, accepts, but doesn't reveal to him that she is carrying his child.

Jennifer gives birth to her son and names him Joshua Adam Parker. She keeps the birth a secret, allowing only Ken Bailey, her assistant, to become aware of her son. She then returns to her practice and soon makes headlines as a successful lawyer. Meanwhile, Michael constantly tries to spark friendship with Jennifer, which she rebuffs at every attempt, reminding him of his earlier tricks. Nevertheless, when her son is kidnapped by a criminal Jennifer is defending, she, in desperation, turns to Michael Moretti for help. After helping her, he seduces her and Jennifer becomes the Family consigliere.
