In 1891, Major Mark Wainwright and a hand-picked team of 10 men cross the Nebraska border in the dark of night and slip into Kansas. Dressed in civilian clothes, they present themselves as volunteers to the Kansas militia-men in the morning; 'I was in the Army fighting the Indians,' Wainwright tells the militia commander, 'I should be able to fight these union boys.' The commander, impressed with Wainwright and his men, assigns them to guard the militia's ammunition dump, just as Wainwright and Colonel Monteith had hoped.
