Kurzbeschreibung:
A young Texas sheriff teams up with a young doctor in the 1800's in a murder investigation. With ideas from a book about new technical advances in finding clues scientifically, he is the first lawman west of the Mississippi to go to trial in a murder without an eyewitness. It is an uphill fight as local people are suspicious of these "new-fangled" ideas from back east. The sheriff not only has to find these clues, he also has to sell the district attorney on using them and a jury on believing them.
