Columbo – Peter Falk and Joyce Jillson in Any Old Port in a Storm (1973)

Adrian Carsini runs a California winery owned by his younger half-brother who reveals he’s about to sell it. This enrages the older wine connoisseur who knocks the young playboy out cold and ties him up in the wine cellar. Soon Carsini has committed a murder and makes it look like a scuba diving accident. The rumpled Lt. Columbo is on the case and is willing to harass everyone – even Carsini’s cold but devoted secretary – until he’s discovered the truth.
