Jennifer has an accident in the park and hits her head, so Jonathan decisively takes her to a hospital. She reluctantly agrees and the doctor diagnoses a minor concussion. Jennifer must stay at the hospital overnight for observation. During the night, she feels restless so gets up, takes a walk through the hallway and witnesses a murder. A nurse is killing a patient. She rushes past Jennifer and escapes. When Jennifer tells the doctor and a sour-faced matron, they don't believe her. Jonathan believes her but is confused. More so when she claims someone is following her.
Of course, this being a Hart to Hart episode she is going to prove everyone she isn't hallucinating and ends up getting gassed and operated on for her troubles
This is one of my favourite H&H, well-acted, suspenseful, especially the finale, and has a great idea. Of course, Robert Wagner and Stephanie Powers acts wonderfully- their characters really care for each other, which is one of the charms of this ace series.
