The greatest adventure of all time begins with Star Trek, the incredible story of a young crew’s maiden voyage onboard the most advanced starship ever created: the U.S.S. Enterprise. On a journey filled with action, comedy and cosmic peril, the new recruits must find a way to stop an evil being whose mission of vengeance threatens all of mankind. The fate of the galaxy rests in the hands of bitter rivals. One, James Kirk (Chris Pine), is a delinquent, thrill-seeking Iowa farm boy. The other, Spock (Zachary Quinto), 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.
With the sequel getting ready to hit theaters it might be time to grab the old one at a discount!
