Magnum, P.I. - Season 3 Episode 22
The Big Blow

A hurricane battering the islands isnt enough to stop Robin Masterss spring equinox party, a lavish event attended by a close circle of friends, but the arrival of an about-to-give birth young woman and two ex-cons intent on grand larceny does. Further complicating matters is Robins assertion that one of his guests is plotting to kill him that evening, and Thomass plans to trap the culprit with the help of Rick and T.C. have been foiled by both the weather and the intruders.
