Young Jimmy is told by his mother that he is due for his vaccination shot, but Jimmy is very afraid. The next morning, Jimmy's grandfather stops by with a story from his past that helps Jimmy feel better. Many years ago, Jimmy's grandfather was a railroad engineer living in a small town. One day, a stranger arrives at the local hotel, but isn't feeling very good. When he faints, the town doctor determines he has smallpox, a very infectious and dangerous disease. Everyone must be quarantined and the town folks must isolate. Luckily, a vaccine has been developed to prevent folks from getting smallpox. Now Jimmy's grandfather was afraid of needles, but to save the town and with a little help from a new friend, he was able to overcome his fear. Jimmy's grandfather travels to the next town to bring the vaccine to the rescue!
