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. Meanwhile, T’Pol and Trip hatch a plan to destroy a key Sphere in the Expanse network, bringing the other-dimensional Sphere Builders, responsible for the Xindi- Human conflict, directly into the fray.
