Star Trek: Enterprise (2001) - 4x14 - The Aenar (3)

Archer and Shran attempt to enlist the help of a secretive xenophobic people on Andoria, who have telepathic powers, known as the Aenar. Having captured a marauding space ship that had been wrecking havoc in the quadrant, the alliance realizes the ships are piloted by telepaths. The problem is, the telepathic Andorians are pacifist who won't even fight to defend their own planet. Archer must find the telepaths, convince them to pilot the captured marauder, and hope they can defeat the remaining threat before the unsteady alliance between the Andorians, Tellarites, and Vulcans collapses into internecine war.
