Pa decides to take Laura hunting with him. When Charles and Laura are getting settled down for the night, Laura trips over her dad's gun and sets it off. Charles is badly wounded. Laura runs to get help, but the only person she can find is a blind person, Sam. Since Sam just recently became blind, he knew his way around somewhat. After getting lost a few times, Sam and Laura finally find Mr. Edwards' home. Mr. Edwards gets a doctor, who saves Mr. Ingalls. Thanks to Laura, Sam learned that just because he was blind didn't mean he had to stay at home and do nothing. (thetvdb.com)
