Take a ringside seat at one of the most controversial trials in American history. The year is 1925, and the students of Dayton, Tennessee, are ready for a summer of fishing, swimming, and drinking root beer floats at Robinson's Drugstore. But when their science teacher, J. T. Scopes, is arrested for having taught Darwin's theory of evolution, it seems it won't be an ordinary summer in Dayton.

As Scopes's trial proceeds, the small town pulses with energy and is faced with astonishing nationwide publicity. Suddenly surrounded by fascinating people and new ideas, Jimmy Lee, Pete, Marybeth, and Willy are thrilled. But amidst the excitement and circus-like atmosphere is a threatening sense of tension--not only in the courtroom, but among even the strongest of friends.
