Most good stories start with a fundamental list of ingredients: the initial situation, conflict, complication, climax, suspense, denouement, and conclusion. Great writers sometimes shake up the recipe and add some spice.
Because Anne Frank: Diary of a Young Girl is, well, a diary, it doesn't follow the classic plot pattern. Nevertheless, it is possible to see multiple conflicts and multiple complications throughout the diary; occasionally, there are resolutions to conflicts, such as Anne’s conflict with her father over her love affair with Peter.
Generally speaking, however, any resolution that occurs is not between characters and occurs internally within Anne.
