Tweelingbroertjes treffen hun moeder op haar boerderij aan met haar gezicht in verband gewikkeld. Ze legt uit dat dit door een cosmetische ingreep komt. Maar wanneer haar gedrag steeds onvoorspelbaarder en vreemder wordt, neemt een angstaanjagend idee bezit van de jongens: het vreselijke vermoeden dat de vrouw onder het gaas helemaal hun moeder niet is.
Nee, helaas is Goodnight Mommy nog niet beschikbaar op Netflix in Nederland.
