Every week before their weekly marital therapy session, estranged couple Tom (Chris O'Dowd) and Louise (Rosamund Pike) meet at a pub to try and get their story straight for the therapist. With each successive episode, we piece together how their lives were, what drew them together and what has started to pull them apart.
Tom promises to be at the session from the start this week.
Tom and Louise discuss the lost passion in their relationship, and if it is something that can be found again.
Tom asks Louise to back him up in a lie with their counselor.
When Tom moves out following a bad session, Louise suggests that it could be the start of a slippery slope.
When Louise complains that Tom's effort feels contrived, Tom realizes that he has to remain himself while acting differently.
Louise admits that she's ashamed of Tom's lack of employment; the couple decide to communicate more openly.
Louise and Tom reflect on why and how they got together in the first place.
When Louise and Tom discuss a breakthrough in their relationship, Louise wonders if it was, in fact, a breakthrough; Louise asks Tom to move back in.
Tom moves back in and feels that his and Louise's issues are resolved; the couple agree that they wouldn't be friends if they weren't married, and look for the right word to describe their relation.
