One outlaw. One relentless lawman.
The Kansas frontier is living in fear.
Deadly train robberies along the Santa Fe Railway have made Colt Blackburn the most feared outlaw on the plains.
Charming, ruthless, and obsessed with building his legend, Blackburn and his gang leave behind stolen payrolls, terrified passengers, and dead railroad guards.
To stop him, the railroad hires Dan Brewer - a former Union scout and experienced tracker known for bringing dangerous men to justice.
As Brewer rides the Kansas corridor searching for Blackburn, he uncovers ambushes, betrayal, and a deadly leak inside the railroad itself.
But Blackburn isn't hiding from the law.
He wants the whole frontier watching.
Now the two men are on a collision course across the open prairie, where every robbery grows more violent and every mistake could mean death.
Because on the Santa Fe Line, legends are written in blood.
