The doc, using the name Louie Pasteur, is quitting his job as a field hand and getting a ride into town when their truck is stopped by a guy who wants Kimble to look at his sick kid. Seems the guy has heard that the doc is known as "doc" for his uncommon medical skills. Plus, the doc is wearing a sports jacket, not common for a field hand. Dick doesn't want to go until the gorgeous Joanna Moore gets out of the guy's car and bats her eyes at him. Anyways, when they get to the remote cabin where they're keeping the kid, Kimble soon figures out the the whole story is a scam. There's a sick kid alright, but he's been kidnapped by these creeps for a ransom. And he's a hemophiliac with a bruise, so he needs attention. The ringleader of the gang is Claude Akins, a rather large and intimidating chap who was thrown out of the NFL for associating with gamblers. Eventually, Dr K knocks out Claude's brother and leaves with the kid. They stop at a house owned by an old woman and her vicious dog. Dick tells the woman he needs to call a doctor but she threatens to sic the dog on them, so Dick tears the end off a cigarette and uses it to start her truck. Is there anything that the doc can't do? So they get to the hospital where Claude is waiting for them. Dick tells the kid to crawl in the door while his stunt double fights Claude. It looks like the doc's undefeated streak is about to come to an end when Claude's brother shows up and cracks a bottle over his head. The cops then show up and brother Dave tells them the kid is in his car, giving Dick a chance to slip away. Of course, before he does he goes into the hospital and tells a somewhat dim witted nurse to take care of Jimmy the kid. The cops question Jimmy about the mystery man who saved his life. Jimmy remembers our hero's name. Louie Pasteur. While the cops look for Pasteur, Richard Kimble heads toward his next adventure.
