On the edge of UPA space a mysterious vessel has appeared.
No one knows where it came from.
It has no callsign or identifying marks.
The vessel simply transmits a standard S.O.S. in a signal that hasn't been used in hundreds of years: Morse code.
While still recovering from their losses on Carlock, the USS Defiance is dispatched to investigate. But when they arrive they discover that every single individual on the ship has already been dead for hundreds of years.
As Captain Mitchell and his crew work to unravel the mystery of this ghost ship, they soon find themselves confronted by something far worse than a simple space mystery:
What killed this crew so long ago is still very much onboard and still is very much alive.
