De film combineert komedie en horror en is een gedurfde en onverwachte kijk op het wereldberoemde verhaal, gezien door de ogen van de stiefzus van Assepoester, Elvira. De bloederige film volgt Elvira terwijl ze strijdt om te concurreren met haar waanzinnig mooie stiefzus in een koninkrijk waar schoonheid een brute aangelegenheid is. Ze zal er alles aan doen om de aandacht van de prins te trekken.
Nee, helaas is Den stygge stesøsteren nog niet beschikbaar op Netflix in Nederland.
