De film speelt zich af in het hedendaagse New York. Twee getrouwde stellen ontmoeten elkaar kort nadat hun zoons ruzie hebben gehad. Michael en Penelope, van wiens zoon zijn tanden eruit zijn geslagen met een stok, nodigen Alan en Nancy uit om de zaken uit te praten. De poging tot het hebben van een beschaafde discussie over wiens kind verantwoordelijk is voor de ruzie, en hoe de ouders invloed hebben op dit gewelddadige gedrag verandert al snel in een grote ruzie.
Nee, helaas is Carnage nog niet beschikbaar op Netflix in Nederland.
