Cover-Up begins with Dr. Charles Aldred (Lin McCarthy) and his daughter Margaret (Margaret Ladd), a nurse, visiting their old friend Quincy (Jack Klugman) for a letter of recommendation as Margaret decides to become a doctor. Later in the evening, a man is rushed into the clinic Margaret works at in cardiac arrest, but the attending physician who is filling in for the normal doctor on duty is not trained in emergency care. The patient dies as a result and the owner of the clinic pressures Margaret to keep quiet over the switch which leads her to seek guidance from Quincy. He performs the autopsy which does not reveal anything unusual, but the toxicology tests uncover what really happened at the clinic that night.
This is an episode dealing with medical malpractice and there is no crime committed or even a mystery for that matter as we see what transpired right in the opening scenes. I'm typically not a fan of the episodes lacking the crime and mystery elements, but somehow this one remained interesting and compelling enough for me to enjoy it. The story was quite reasonable and I didn't find any huge plot holes unlike several other Season 5 episodes up to this point.
Overall this is a pretty decent and entertaining plot which is a little different from the norm and moves along at a good pace which I highly recommend viewing.
