Draper's Tours-gastvrouw Gemma Draper en haar trouwe buschauffeur Terry moeten Mildred en Hilda ophalen. Deze zijn onderweg naar een begrafenis in Middlesbrough. Tijdens een hevig onweer begeeft echter hun bus het. Nu worden ze gedwongen om hun toevlucht te zoeken op een sinister en vervallen caravanpark met de naam Shady Creek Caravan Park. Hier maken ze kennis met een paar bijzondere bewoners, maar al snel leggen de bezoekers en bewoners één voor één het loodje.
Nee, helaas is Dial M for Middlesbrough nog niet beschikbaar op Netflix in Nederland.
