Sickbay reports a young woman of unknown origins is in a coma in Sickbay.  Upon examination, it is discovered that she is Argovan, a previously encountered humanoid species.  Upon searching the computer, they find that the Argovans are a xenophobic society in the extreme reaches of the Federation.  The science and medical teams begin a passive examination of the woman and reach out to Starfleet for guidance.  Soon an Argovan transport arrives, requesting the return of their citizen rather urgently.  Starfleet advises a soft touch and diplomatic overtures to get a sense of the Argovans to extend connections with them further.  The crew is pressed into diplomatic action when the transport captain refuses to come aboard and demands the Argovan woman back.
