Raiders who seem intent on destroying every ranch in the valley are terrorizing the district of Mountain Peak in Arizona. When rancher David Meredith becomes their latest victim, it opens a new chapter in the violent and bloody history of the town of Mountain Peak. Caught up in the maelstrom of events is David's troubled younger brother, Bart Meredith. He is aided - and sometimes led - by his heavyweight father, who shows an amazing talent for ingenious stratagems, and Jane Talbot, a courageous young woman who herself becomes a target for the terrorists. Can the unlikely team of father and son avenge David Meredith and unmask his killer, or will they join him in death?
