Private investigator
Private investigator Jerry Church (Knowles) has just married his longtime fiancée, Kit (Gwynne). Defense attorney Dudley Crispin (Hinds) and Church's former police partner Capt. Hurd (Edmund McDonald), talk Church into taking one last case: investigating a string of murders committed by someone calling themselves Dr. Rx where the victims have been five clients that Crispin had successfully defended in court.
