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.

Jill Danko is seriously wounded by a seemingly demented gunman while dining with her husband Mike. Later, they find out that the gunman is unable to be prosecuted in court, because he is suffering from a brain tumor which appears to be the cause of his action. The rookies take it upon themselves to prove the man is dangerous and can place society in jeopardy.
