The Andorians and the Vulcans are locked in battle over a small planet, situated on the frontier between their two systems. Both sides claim that it belongs to them — the Andorians refer to it as "Weytahm," while the Vulcans call it "Paan Mokar." Andorian Commander Shran has landed a force on the planet and occupied the settlement. Now, the Vulcans are calling for a cease fire and Shran wants Archer to help the two sides negotiate. Vulcan Ambassador Soval is reluctant to bring Archer in as mediator, but three Vulcans have been taken hostage, and Shran has made his position clear — he only trusts Archer.
