The Enterprise crew pays a friendly visit to an ancient Vulcan spiritual sanctuary, despite T'Pol's concerns that her human colleagues will be an awkward and disruptive presence there. Upon landing, they discover that the monastery has been forcibly taken over by the Andorians, a paranoid and highly excitable race of aliens with a long history of conflict with the Vulcans. Archer soon discovers that the Enterprise crew has gotten in the middle of an interstellar Pandora's Box and now must find a way out.
