Amid a ruse gone wrong, Worf and his away team of B'Elanna Torres and Ro Laren find themselves imprisoned by Orion pirates wary of the supposed Maquis separatists. Meanwhile, in the captain's chair of the Defiant, Spock struggles to defend the ship with Lore's musings of chaos in his ear.
Captain Worf struggles to maintain order among the Defiant's crew with the addition of two reluctant new recruits, causing friction on board the stolen vessel. And with Klingon adrenaline still surging through Kahless' veins, the need to find-and stop-him has never seemed so urgent.
With the fugitive criminal Akris having escaped into Romulan space, Nyota Uhura and the crew of the USS Enterprise must quickly devise a plan if they're to prevent an alliance between the agent of chaos from a parallel universe and one of the Federation's most dangerous enemies.
Akris-a maniacal doppelganger of Chekov from a parallel universe-has begun working with the Romulans on a superweapon with a promise to reduce the Federation and its allies to ashes. And with half the bridge crew in Romulan custody, it's up to Spock and McCoy to hold down the ship and devise a plan to get their captain and crewmates out of enemy hands!
Tensions are at an all-time high with Chekov in a dire medical state while his evil doppelgänger, Akris, is supplying the Romulans with the Nightbringer weapon. The Enterprise crew's mission is clear: infiltrate the Romulan dreadnought and destroy the Nightbringer before Akris can bring the destruction he's inflicted upon his universe into theirs. But can Kirk and Nyota set their differences aside to ensure a peaceful resolution and avoid sparking a war with the Romulans?
