ARCHER LEADS HIS NEW XINDI ALLIES AFTER THE SUPERWEAPON AS T'POL AND ENTERPRISE HATCH A PLAN TO DISABLE THE SPHERE NETWORK, ON A REBROADCAST OF "STAR TREK: ENTERPRISE," FRIDAY, SEPT. 3

"Countdown" -- Archer and his new Xindi allies must launch a full-scale assault on the superweapon speeding towards Earth and its thieving escorts, the rebellious Reptilian and Insectoid Xindi, before a kidnapped and brainwashed Hoshi can decrypt the weapon's encoded arming mechanism and unleash its devastating power, on a rebroadcast of STAR TREK: ENTERPRISE, Friday, Sept. 3 (8:00-9:00 PM, ET/PT) on UPN. Robert Duncan McNeill directed the episode from a script by Andre Bormanis and Chris Black. (Originally broadcast 5/19/04)

Meanwhile, T'Pol and Trip hatch a plan to destroy one of the massive metallic spheres responsible for all the space anomalies in the region, bringing the Sphere Builders, aliens responsible for originally pitting the Xindi against Earth, directly into the fray.
