The bond between wandering cowboys Buck Medwell and his younger brother Skip has always been fractious. So when Buck is forced to bust his kin out of jail following their pay-off at the end of a cattle drive to Newton, Kansas, the writing is on the wall. Their flight from the law into neighbouring Colorado leads to a split when bad blood finally spills over. But fate has a habit of playing a wily hand, resulting in the pair unexpectedly being thrown together once again. When Skip finds his life on the line, his brother needs to exert all his ingenuity to save the kid from the unscrupulous hands of arch schemer Diamond Jack Deakin.
