Jim East was a working cowboy on the LX Ranch in the Texas Panhandle, just trying to earn an honest living, when his plans took an unexpected turn. While trying to solve a rustling problem for the LX, he was recruited by legendary lawman Pat Garrett to join a posse of tough men to find and arrest outlaw Billy the Kid. When he returned to Tascosa, he was elected sheriff of Oldham County, charged with keeping the peace in the growing community and its population of gunmen, shady gamblers, rustlers, and thieves in a rowdy, hard-drinking town.
