Llewellyn Cooper and his aunt Julia run Curio Cabinet in New York City's West Village, where the clientele is as strange as the junk being amassed in their secondhand shop. Llewellyn and Julia have been as thick as thieves his entire life, and Llewellyn can't imagine being anywhere else six days a week—even if Julia's bizarre habits and inappropriate conversations drive him crazy. That's family, though, right?

When Llewellyn drums up the nerve to chat with a routine customer—in part due to curiosity, as Henry McLaughlin returns time and again to purchase nothing but old photographs, but also because the bearded and bow tie–wearing man is the finest thing to ever step foot inside Curio—it seems like Llewellyn will finally have a plus-one for future RSVPs. But just when things start looking up in the romance department, it turns out Henry might be too strange for the Cooper family.

And that's saying something.
