The Enterprise is headed for some much-needed shore leave on the planet Risa. But the ship gets reassigned to head to the planet Mazar to pick up a Vulcan Ambassador. The Ambassador is being expelled from the planet due to alleged criminal misconduct. In actual fact, the ambassador is on a special mission, and has difficulty telling Archer exactly what is going on. Things get even more complicated for Archer when the Enterprise is pursued by the Mazarite equivalent of the mafia, leaving it to fight its way to the Vulcan rendezvous point.
