By 1870, there has been 10 years of cruel war between settlers and Cochise's Apaches. Ex-soldier Tom Jeffords saves the life of an Apache boy and starts to wonder if Indians are human, after all; soon, he determines to use this chance to make himself an ambassador. Against all odds, his solitary mission into Cochise's stronghold opens a dialogue. Opportunely, the president sends General Howard with orders to conclude peace. But even with Jeffords's luck, the deep grievance and hatred on both sides make tragic failure all too likely.
