A gang of robbers armed with a union army cannon rob the bank holding bounty Killer Acquasanta Joe's earnings to date. He pursues, crossing and double crossing along the way.

At the end of the American Civil War, jobless soldiers sometimes form gangs, and one is led by a former colonel, still using his weapon of choice: an Army cannon. When they rob Acquasanta Joe's life-savings, the killer goes after them in earnest, sometimes using other killers as temporary friends,all after the gold prize. Estella provides Joe with information, and some companionship--as a silver prize that comes between Joe and the colonel. Will Joe's bow-and-arrow be enough against a cannon?—Artemis-9
