Almost a year after the S.C.E. crew on the da Vinci helped Lieutenant Nog of Deep Space 9 â"¢ salvage the hulk of DS9's sister station Empok Nor, a booby trap left behind by the Androssi threatens the Bajoran system. But the potential damage may be greater than the combined crews of the da Vinci and DS9 can handle, as the threat stretches across two universes -- and their only hope for survival may rest with their long-dead crewmates 111 and Kieran Duffy!
