If like me you have problems writing one page synopsis’, then this might be of help.
Amanda Patterson, of Writers Write, has produced this info graphic to help people write them:
Source: How to Write a One Page Synopsis by Amanda Patterson, http://writerswrite.co.za/how-to-write-a-one-page-synopsis-1
This does reference the Basic Plot Structure, available here: http://writerswrite.co.za/basic-plot-structure-the-five-plotting-moments-that-matter. I know I definitely need to use this since I am horrible at writing synopsis’ and I hope this helps others.
