In this case, the farmer probably had a prejudice against inmates and thought hey all were vicious criminals, but when he worked together with them to save the town from flooding, he realized that they were not as bad as he thought they were before. Many times our thoughts are shaped by stereotypes, e.g. this particular type of person is no good, until you get a chance to interact with someone that belonged to that "bad group" and realize that they are not like you thought they were. It can also work differently, you might consider that a specific group of people are very "cool or good" people, but once you have a chance to interact with them you realize that your expectations were probably too high.
