Gunsmoke #400, "Big Chugg Wilson," a seemingly innocent flirtation between saloon girl Lori and a rough buffalo hunter spirals into violence and obsession. When the unwashed and lonely Chugg Wilson rides into Dodge City to sell his hides, Lori playfully teases him at the Long Branch, much to the concern of Roque, a ranch hand who has feelings for her. Kitty Russell warns Lori that she might be attracting more attention than she intends, but Lori dismisses the danger, insisting she's just having fun. She promises Chugg a drink later, not realizing how seriously he takes her casual attention.

When Chugg returns that evening expecting Lori to keep her promise, the situation turns dark. Lori tries to brush him off, explaining she was only teasing, but Chugg refuses to accept her rejection. When Roque attempts to defend Lori and escort her home, the massive buffalo hunter becomes violent, leaving Roque badly hurt and claiming Lori for himself. What began as playful banter transforms into a dangerous confrontation that threatens everyone involved.
