The Alpha Quadrant is on the brink of war, after a Federation Diplomat is assassinated on the planet Fenris. Admiral Alynna Necheyav is trying to use leverage against Fenris and the Fenris Rangers to force Seven of Nine to surrender to her. However, a new variable has been injected into the crisis, as the Klingon Empire, under Chancellor Worf, has warned The Federation against attacking Fenris. Closer to Earth, Seven of Nine, and some of her former Voyager crew mates are searching for a suspected XB prison.
