This is yet another episode that proves that Dr. Quincy should NEVER take a vacation. That's because repeatedly on the show, whenever he travels (on vacation or to a convention) bad things will happen and he'll need to do coroner stuff--and often this means autopsies. While having this happen once or twice is bad enough, but EVERY time Quincy travels?! The show is a bit unusual, as Diana Muldaur returns to the show as the same character she played a year earlier. Now having a guest actor appear several times on the show isn't odd, but they usually play different characters. This time, Muldaur plays the Public Health Officer once again--and Quincy's love interest.
The pair go on vacation to Tahiti. The cruise back looks like it will be wonderful, but wouldn't you know it, folks start dying!! It's an odd case, as they hallucinate and end up killing themselves or others--as if they are having a bad acid trip. What is the culprit? Well, you'll have to watch both part one and part two to know the answer to this one.
Part two begins with the two idiots jumping off the boat and swimming to shore. Unfortunately for them, it is NOT a jump to safety as the local authorities vow to shoot them in order to prevent the disease from infecting their people (which is understandable). However, Mark and Sam come in to the rescue--but end up getting exposed to whatever it is in the process. And, it (not surprisingly) ends with the discovery of the cause of the outbreak as well as Quincy and the gang at Danny's to celebrate (what else?). Overall, entertaining but also a VERY familiar theme...Quincy DON'T go on vacation!!!
