When archivist Sol meets Elsie, the larger than life widow of a moderately famous television writer who's come to donate her wife's papers, there's an instant spark. But Sol has a secret: he suffers from an illness called vampirism, and hides from the sun by living in his basement office. On their way to falling in love, the two traverse grief, delve into the Internet fandom they once unknowingly shared, and navigate the realities of transphobia.
