February 14, 2154.  With Earth in sight, Archer, Hoshi, Reed and a small team helped by Degra and humanoid and arboreal Xindis, race to intercept the charging superweapon, sneak past the Xindi Reptilian onboard and disarm it from within, but while the gambit could save humanity, it may cost Archer his life. Back in the Delphic Expanse, T'Pol and Enterprise attempt to obliterate a key Sphere in the region before the furious interdimensional Sphere Builders tear the ship apart and the region's degenerative effects kill the crew. But in an ultimate twist, the builders change the History in order to win the war... before it even begun. To be continued in the 4th season.
