In 1914 Charlie Chaplin debuted with the Mack Sennett shorts for Keystone. These shorts were made in rapid succession and while some are great, some are ok (like this one) and some are bad. Despite the results they were all released in theaters. These early shorts are pretty much like home videos (like the ones played on AMERICA'S FUNNIEST VIDEOS) with people that do stupid things and in the end they have pratfalls. His tramp character (that debuted here) was still evolving as he switched to Essenay studios a year later. He stopped this evolution process with his full-length movies in the 1920s.
In this short, as I said in the summary, there isn't much plot. The Keystone crew went on a kid auto race and they told Chaplin to just wander around and coming in and out of the track. The only thing that happens beside this is that he is sometimes punched by few adults for getting in the track. The only thing for which this short is important is because we have a first shot of Chaplin's most famous character.
