Gunsmoke #404, "Trojan War," finds Marshal Matt Dillon confronting the notorious Pueblo gang when they arrive in Dodge City. The trio of outlaws, Ed and Rio Parks and Chuck Evans, have a fearsome reputation for stage robberies throughout the western territories, and Dillon wastes no time warning them to keep their noses clean in his town. When the gold dust shipment stage from Buckeye fails to arrive on schedule, the marshal's suspicions are confirmed. He and Chester discover the robbed stagecoach with the driver and guard shot dead, the strongbox emptied, and a woman's carpetbag inside with no sign of its owner.

Following the killers' trail through the darkening wilderness, Matt and Chester track the gang to an abandoned campsite where they make a grim discovery. They find Helen Ford, a female passenger from the stage, shot and left for dead by the fleeing outlaws. As the dying woman struggles to identify her attackers, Dillon faces the challenge of bringing the ruthless Pueblo gang to justice for robbery and murder.
