Professor Dawn Summers notices a very strange language on a whiteboard in her colleague's, Professor Epps, office. She ends up working for the FBI and an adventure begins. Meanwhile, Buffy is pursuing Don, and what's Charlie's girlfriend doing?

Dawn is studying at Oxford. Even though there's no hellmouth in England, trouble finds her anyway. Although the crime looks like human-caused murder, with ties going back more than a century, if Dawn and Buffy Summers are in the neighborhood is it not likely that the supernatural will show up? The crossover includes BtVS, Midsomer Murders, and Inspector Lewis.
