United

Archer tries to unify the Andorians, Tellarites, and Vulcans in a plan to capture a remote-controlled Romulan marauder ship threatening to destabilize the region. But, a desire for vengeance interferes with Archer's attempts to ally Shran and the Tellarites, where Archer and Shran fight to the death, almost. Trip and Reed probe the inner workings of the unmanned Romulan warship and must outwit their captors to escape.
