Master Chief made this machinima because he was working for Douchebag Studios to create a more serious movie than his last one, so that he and Skyler Loveheart would make money. This movie was intended to prove that Master Chief was capable of making a good movie.
The movie took seven weeks to create. When it was finished Chief showed it to Skyler. It turned out to be terrible and very short, which put Skyler in to a rage that made him attempt murder of Chief.
The movie was about a soldier who tries to battle aliens, against all odds. After killing them, another person congratulates the soldier on his success. After that, the movie ends. It is less than a minute long.
