Gunsmoke #425, "Bad Seed," finds Marshal Matt Dillon on his way back to Dodge from Fort Larnard when an unexpected visitor enters his camp. A young woman named Trudy Trent, claiming to be starving and desperate, begs the marshal not to send her back to her father. She paints a dark picture of life with her Pa, describing him as a violent drunk who mistreats her terribly. Despite her pleas and increasingly inappropriate advances, Matt insists on taking her home the next morning.

When they arrive at the ramshackle Trent farm, Matt meets Asa Trent, a slovenly drunk who alternates between professing affection for his daughter and threatening the marshal. The tension at supper is thick as Trudy recounts disturbing incidents from her past, including a Christmas when her drunken father accidentally set her on fire. Convinced that the girl's situation is genuinely dire, Matt agrees to take Trudy back to Dodge with him despite Asa's threats and warnings. But as Matt settles into the barn loft for the night, he senses something isn't quite right about the whole situation.
