Helmed by Captain Rudolph Ransom, the Equinox has been trapped in the Delta Quadrant even longer than the Voyager and the ship and crew show the scars of a constant struggle to survive. But Ransom and his people are hiding something as well: a shocking secret that will ultimately pit captain against captain, starship against starship, in an explosive conflict that may cost Voyager the life of her captain!
