Cynthis (Harriette Johns) huurt de privédetective Slim Callaghan (Derrick de Marney) in wanneer haar oom zijn testament verandert in haar voordeel, althans dat beweert zij... Wanneer Slim ontdekt dat haar oom reeds gestorven is, zijn de voormalige drie begunstigden in zijn ogen niet meer verdacht, maar Cynthis nu wel.
Nee, helaas is Meet Mr. Callaghan nog niet beschikbaar op Netflix in Nederland.
