Kimble meets a kindred soul: another fugitive running from a false charge and searching for someone. This one is played by Fritz Weaver, who has been falsely convicted of embezzlement and who, in a near crazed state wants to kill the leading witness to avenge his false and damning testimony. He's suffering from a rare illness, which Kimble recognizes and goes to the nearest town to try to get medication for. He's captured by the police, not as Richard Kimble but as someone who knows where Weaver is. This is the town where he was convicted.
But Weaver's situation has changed: before he died the bank president confessed to embezzling the money. The witness has recanted his testimony. Weaver is a free man. His daughter, (Brenda Scott) convinces Kimble to contact him to tell him this. He's not likely to trust the police as they tricked him into surrendering when he was first arrested, (we aren't given the details). He'll just think it's another trick. Maybe Kimble can convince him that there's no reason to run or kill anyone. He insists on going to Weaver alone: if he saw police cars, he wouldn't believe it. So they let him go. But then the police find out who he really is and they go after Kimble.
It's another nice twist from the writers, with a good scene where Kimble tells Weaver what it's like to be wanted for murder, as opposed to a lesser crime.
