Mary Lou, de prom queen die in de jaren '50 door haar vriendje werd vermoord, is opnieuw uit de hel ontsnapt en terroriseert opnieuw de gangen van de Hamilton High School. Mary Lou komt meer en meer in vorm en het dodental in de school loopt steeds hoger op, totdat de klassen wel erg leeg worden.
Nee, helaas is Prom Night III: The Last Kiss nog niet beschikbaar op Netflix in Nederland.
