Kaja is de ultieme optimist. Zelfs het feit dat ze getrouwd is met een man die nauwelijks interesse in haar heeft, kan dit niet veranderen. Maar als haar nieuwe buren het perfecte stel lijken te zijn, begint er toch iets bij Kaja te knagen. De nieuwe buren zijn succesvol, knap, zingen in een koor en hebben zelfs een kind geadopteerd uit Ethiopië. Kaja leert via hen een totaal nieuwe wereld kennen, waardoor haar eigen wereld compleet op zijn kop komt te staan.
Nee, helaas is Happy, Happy nog niet beschikbaar op Netflix in Nederland.
