A dinner party finds Quincy and his boss Dr. Asten, at the home of Quincy's former high school sweetheart. He is weary of seeing her again because she was unstable the last time he had seen her, but appears normal now. The next morning finds that a top politician, Powell Dixon had died while at the house. An autopsy clears Jeannina, Quincy's former love, of any wrong doing. But when an explosion kills her too, Quincy knows that these cases may be murders.
