They changed the opening narration for this one. It's no longer an "irony" that Kimble is innocent. Now "laws are made by men, carried out by men and men are imperfect". Somebody must have complained about the law being "ironic".
Kimble is a farm worker again but because he's called "Doc", he's pressed into service to administer to a hemophiliac boy who has been injured. He senses something wrong and boy is it: the kid has been kidnapped and the authorities are trying to find him, which means they will also find Kimble. Kimble winds up escaping with the kid, (he manages somehow to start a car with a cigarette: I didn't know you can do that), and tries to get the boy to a hospital before the gang can recapture them or the cops can catch up with all of them. It winds up with a rather absurd fight scene between Kimble and the leader of the kidnappers, (Claude Akins) outside the door to the hospital. Nobody comes out to see what the commotion is. This allows Kimble to be on his way to the next adventure while the boy is discovered by the hospital staff.
Tatum O'Neal's Mom, Joanna Moore, plays Akin's girlfriend. She would get along with Madlyn Rhue's "Sophie" in the previous episode. They have the same heart rate.
