While on patrol, the Basroil and another assault ship, the Seigroil, are hit by enemy mines. They wind up adrift, stranded in “Plane Space”. They have no sensors and systems begin failing throughout both ships. They soon come up with a plan to transfer all the crew and usable materials from the Seigroil to the Basroil, but once they do, the Basroil crew learns that the Seigroil bridge crew is trapped and cannot escape. Now, alone in the dark, the Basroil can see some unidentified ships coming toward them. But, are they friend or foe?
