Former professional baseball player Justin Piersol needs a new life after a career-ending injury, and his job as a high school baseball coach isn't exactly fulfilling. Still, things are looking up: he finds the perfect room in an apartment in Brooklyn with Mark, who writes a popular column on sports statistics.
Mark is nerdy and socially awkward and intensely shy, and he immediately develops a terrible crush on Justin, who barely seems to notice him. As they get to know each other, Justin admits he misses playing baseball, that coaching doesn't scratch the itch. Mark confesses he thought he'd be married by now, that he wants a serious relationship. So they make a pact: Justin will help Mark find a man, and Mark will help Justin find something he loves more than baseball.
They put their plan into action… and then life gets complicated. Mark meets a nice guy named Dave, and Justin is suddenly crazy with jealousy. Justin realizes he wants to let go of the past and focus on the present, but as Mark and Dave become an item, Justin fears he's too late.
