While the Constitution explores uncharted territories, it finds itself in an area where no life has developed; however, when two ships are detected on long-range sensors, the crew sets a course to investigate. They find both vessels adrift in space with only one survivor barely alive. As the crew helps this individual, they discover she is Vidiian and has never been infected by the deadly Phage virus. She explains that she is from a world where other Vidiians have not been taken ill and asks if they can return her home. After conducting further scans of the region, the crew finds the world inhabited by the Phage-free Vidiians; furthermore, this world is near an interspatial flexure, a rare phenomenon that, when it appears, could send the Constitution to the Nacene Reach. However, the Vidiians are in a tough fight against those who want revenge for what their brethren have inflicted on them with their organ-harvesting operations. The Kazon have taken a defensive posture near to where the flexure opens. The Vidiian’s defence forces are equally matched to the Kazons. Attempting to find a way past both sides, the Constitution crew must decide which side they will support to get home.
