In the spring of 1880, Railroad Detective Charles Gentry, better known as CW Gentry, is dispatched to the rough and tumble town of Tin Cup, located in the heart of the mineral belt, deep in the Colorado Rockies. At the time, CW is considered to be one of the railroad's best detectives. The reason is simple...he's the man that gets results. Fearless, ruthless, and relentless are the words most often used to describe him by those in the head office. His assignment is to end a string of train robberies that have recently plagued the South Park Division of the Union Pacific. Although it's the type of assignment CW thrives on, romance, murder, and a tragic train wreck are just a few of the sharp curves in the track ahead. And in the end... justice comes in a very unexpected way.
