The document outlines initial plans for a short film project, including: 1) Brainstorming ways the phrase "that wasn't supposed to happen" could be incorporated, such as through an accidental event. 2) Keeping sound effects simple to make some more dramatic. An ongoing backing track will be used with sharp sound effects between. 3) Possible story ideas involving a generator, exploding light bulbs, and a horror creature jump scare at the end incorporating the phrase.
