Duty interferes with the crew's first shore leave when the Enterprise is sent to the planet Mazar to fetch a distinguished Vulcan ambassador accused of criminal misconduct. The mission disturbs T'Pol, who's a great admirer of the diplomat.

T'Pol talks Archer into joining the shore-leave party on the planet Risa, where he encounters a troubled alien beauty; Hoshi learns a new language from a local man; a pair of aliens take advantage of Trip and Reed; Dr. Phlox's hibernation is disrupted by Mayweather's injury.
