How can you be certain he is the one, if he is the only one?
As far as Anna (Rebecca Hall) is concerned, she couldn’t be happier with her boyfriend, Will (Dan Stevens). They’re talking about marriage and hoping to close a deal on a new Brooklyn brownstone together. While out at dinner for her birthday, Anna’s brother, Hale (David Joseph Craig), and his partner, Reece (Morgan Spector), innocently point out that she’s never been with anyone other than Will. It doesn’t take long for that seemingly innocuous observation to alter Anna and Will’s future. At the same time, Hale and Reece struggle to take the next major step in their own relationship: starting a family.
