A man disguised as a police officer kidnaps the daughter of a wealthy family, the Sloans. The Police Squad are quick to react to the kidnapping. The kidnapper writes a ransom note demanding two hundred thousand dollars, Meanwhile, Danko, Webster and Gillis notice that Ryker appears to be distracted. A fainting spell places him in the hospital, where he confides in Jill that the kidnapped girl may in fact be his biological daughter.

Responding to a robbery complaint, Webster and Gillis arrive at the building and enter into a criminal-chase. Thinking he is being fired at, Gillis returns gunshots. He strikes one of the criminals, David Palmer, only to find out that the teen is unarmed and now gravely injured. Gillis is overcome with guilt. An inquest is scheduled until the teen dies on the operating table. Later that evening, Gillis receives the first of several anonymous phone calls informing him that he did not kill David Palmer; the Squad, consequently, begins further investigation.

After three woman are murdered, the Police Squad takes action. In order to solve the mysterious murders and prevent future ones, the Squad welcomes two women officers to the force, Dawson and Conway. A plan is created which places Dawson and Conway in an apartment complex together, with Webster and Gillis across the hall.

In an effort to prove he's no 'old man', Officer Danko chases down a fleeing criminal. While he succeeds in apprehending the thief, his partners Webster and Gillis fail to catch the criminal's brother, who is also running from the law. Danko testifies in court against the criminal he caught, thereby infuriating the brother who is unassumingly observing in the courtroom. Consequently, he begins to terrorize Danko's wife, Jill, with mysterious phone calls. Not wanting to upset her husband, Jill confides in his co-officers. When Danko finds out, he is confronted with the issue of whether or not to change his testimony in court, to appease the terrorizing felon and save he and his wife.
