It's time for a good ol' fashioned Supernatural ghost hunt.

The Winchester brothers have the Mark of Cain hanging over their heads, but Sam (Jared Padalecki) and Dean (Jensen Ackles) will find something to salt and burn in the meantime. Hopping back into the Impala, the boys will track down a series' of computer related hauntings during episode 13, "Halt & Catch Fire."

Somehow, a ghost will find its way into the circuits of our wired up society, using any available technology to take down a group of college students.

The second of two monster of the week episodes, "Halt & Catch Fire" will air directly before Cain's (Timothy Omundson) episode 14 return. "The Executioner's Song" will undoubtedly bring the story back around to Dean and his pesky Mark, but the Winchesters will hopefully get to experience a flash of normalcy (or what passes for normal in their paranormal world) during "About a Boy" and "Halt & Catch Fire."

In the meantime, however, Sam and Dean will have to deal with Charlie's (Felicia Day) return from Oz in next week's "There's No Place Like Home" (see video below).
