In the nine decades following Zefram Cochrane's visionary warp flight in space and the First Contact that followed, the human race has been slowly guided by the Vulcans toward developing the Warp Five engine. Mankind is at last able to explore the virgin depths of space with a revolutionary new starship, the Enterprise NX-01, under the command of Captain Jonathan Archer. Plans to launch Enterprise are moved up when a Klingon courier is shot down by unknown assailants and crash-lands in Broken Bow, Oklahoma. Feeling that the Vulcans have been condescending toward mankind for years, Archer insists it's the humans' responsibility to return the injured Klingon to his homeworld alive. Archer is fully backed by Starfleet Command, and the Vulcans' objections fall upon deaf ears.
