Tyler Brandon, Stanford's bad boy professor, is the head of the Archaeology Department, and is called "Indiana Ty" by his students. He enjoys an adventurous lifestyle exploring the world for new finds. As a certified hunk with a love 'em and leave 'em reputation with the ladies, he is sought after by every star struck coed on campus. He is seen at University events with a different gorgeous woman on his arm each time. Ty's teaching assistant, Hannalore Bascomb, is as buttoned up a young woman as could be found on a modern California campus. Hanna is torn when she has an opportunity to accompany Dr. Brandon on an expedition to view a recently discovered cenote, or sinkhole, in Guatemala. Which will win out - the excitement of the find and the opportunity for some hands-on field experience to broaden the scope of her doctoral thesis or the danger of too much exposure to the handsome Ty Brandon?
