Howard Duncan, a disgraced army officer, drummed out of the cavalry by Colonel Mackenzie for an unprovoked attack upon a peaceful Indian village, organizes a band of renegades to avenge himself upon Mackenzie and his former regiment. After Duncan wipes out patrols sent to deal with his band of cutthroats, Mackenzie decides to take lead a picked band of his raiders to eliminate the threat to his command.
