Gwen Cummings is een succesvolle New Yorkse schrijfster, die er een wild uitgaanspatroon op na houdt. Ze duikt op in alle trendy clubs en is in beschonken toestand te vinden op elk feestje. Haar leven neemt een radicale wending wanneer ze op het huwelijksfeest van haar zus Lily volledig door het lint gaat. Ze wordt veroordeeld tot een afkickkuur van 28 dagen in een ontwenningskliniek. Gwen moet zich houden aan een strikt schema vol regels en afspraken. Ze komt al snel in conflict met zichzelf en alle andere patiënten. Maar de cynische Gwen wil zich niet neerleggen bij de normale gang van zaken in het instituut.
Nee, helaas is 28 Days nog niet beschikbaar op Netflix in Nederland.
