In Victorian-era Ireland, portrait photographer Brock Blennerhasset has made a successful career out of commemorating the recently deceased. When one of his photographic plates goes missing - putting his reputation on the line - Blennerhasset hires eager gravedigger Conall Molloy to help find it.

Blennerhasset and Molloy are trapped in a coastal town during a storm where some ghostly occurrences make them feel most unwelcome.

Blennerhasset and Nancy are forced to delve into the seedy underbelly of Dublin's criminal underworld after both Molloy and their camera equipment go missing.
