A colony ship careens out of control through space on the border between the Federation and the Klingon Empire. A joint rescue mission made up of both Klingon and Starfleet engineers is sent to investigate. But the S.C.E. team from the U.S.S. da Vinci and their Klingon counterparts soon find themselves with a more difficult problem than they realized. The colony isn’t just out of control — it’s dying.

The inhabitants of the colony ship are a pre-industrial society that has no inkling of their deadly fate. Can Federation and Klingon engineers work together to save the colony ship from total destruction?
