Na 14 jaar huwelijk kunnen Tom (Joel McHale) en Janet (Kerry Bishé) nog steeds niet van elkaar af blijven. Als ze ontdekken dat hun vrienden wrok koesteren over hun constante openbare uitingen van genegenheid, begint het paar de loyaliteit van iedereen om hen heen in twijfel te trekken. Dan brengt een bezoek van een mysterieuze vreemdeling (Stephen Root) hen in een existentiële crisis, wat leidt tot een lijk, veel vragen en een zeer spannende vakantie voor koppels in deze donkere romantische komedie.
Nee, helaas is Happily nog niet beschikbaar op Netflix in Nederland.
