The night after another unsatisfactory New Year's party, Tim's father tells his son that the men in his family have always had the ability to travel through time. They can't change history, but they can change what happens and has happened in their own lives. Thus begins the start of a lesson in learning to appreciate life itself as it is, as it comes, and most importantly, the people living alongside us.

The fate of the galaxy rests in the hands of bitter rivals. One, James Kirk, is a delinquent, thrill-seeking Iowa farm boy. The other, Spock, a Vulcan, was raised in a logic-based society that rejects all emotion. As fiery instinct clashes with calm reason, their unlikely but powerful partnership is the only thing capable of leading their crew through unimaginable danger, boldly going where no one has gone before. The human adventure has begun again.
