Loner 4: The Big Gundown
Using an old cannon that once belonged to Napoleon's army, an outlaw gang has been bringing trains to a halt and then robbing them. But when the gang turns their big gun on a town, killing several innocent people, The Loner has to choose sides. Now Edward Sheffield--one of the owners of the railroad--wants to hire Conrad Morgan, known as The Loner, to wipe the gang off the map.
