Celeste and Jesse Forever

Celeste (Rashida Jones) and Jesse (Andy Samberg), who met each other when they were young, have been together for a long time. After six months of separation, they still enjoy each other and spend every day together. Over dinner one night, their mutual friends Beth (Ari Graynor) and Tucker (Eric Christian Olsen) ask them what's going on.

Beth tells them it's not normal for them to act like there's nothing wrong when they are in the process of getting a divorce. Celeste and Jesse maintain that they are just best friends and are better off this way rather than in a failing marriage. What follows is the couple's struggle to maintain their close friendship while exploring new relationships with other people.
