"Zero Hour" -- With Earth in sight, Archer, Hoshi, Reed and a small team 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, on a rebroadcast of STAR TREK: ENTERPRISE, Friday, Sept. 17 (8:00-9:00 PM, ET/PT) on UPN. Allan Kroeker directed the episode from a script by Rick Berman and Brannon Braga. (Originally broadcast 5/26/04)
