"I am Spock...I hold the rank of Commander in the Starfleet of the United Federation of Planets; I serve as First Officer of the Starship Enterprise. I am the son of two worlds. Of Earth, whose history is an open book...and of Vulcan, whose secrets have lain hidden beneath its burning sands...Until now..." And Spock - torn between his duty to Starfleet and the unbreakable ties that bind him to Vulcan - must find a way to reconcile both his own inner conflict and the external dilemma his planet faces...lest the Federation itself be ripped asunder.
