When the story begins, a rich big-shot, Clark Blanchard, picks up Jessica at the airport and whisks her off to see his wife Ginny (Lois Nettleton). Apparently Ginny and Jessica are old friends (a COMMON trope for this show). What Jessica doesn't know is that Clark is a big dumb jerk-face...who treats others terribly and beats Ginny. So, when Clark is found assuming room temperature after being struck with a fireplace poker, Jessica investigates to see what REALLY happened and, more importantly, WHY.
This is a good episode because it addresses a sad problem, domestic violence...and it deals with it very well. A bit surprising that Chad Everett would agree to play such a disagreeable character...but it's well worth seeing.
