John, Eliza, Jessica, Lily, Mike, Franck, Simon, and Victoria are the characters created in Anonymous’ mind. They go through a series of events and happenings that finally make them to understand the difference between reality and dream, and realize the true spirit and nature of their creator, Anonymous.

If the reveal at the end of the story, is the characters are all a figment in the mind of Anonymous, then I would not add that to the logline. I would not give away a big reveal.

So basically this is a 'it was all a dream' premise... Not sure this would fly nowaday and age.

Also, as DPG suggested, best to focus on one main character with one objective goal in a logline. Check out some of the other loglines and comments on this website, as well as the Training tab on the top bar for more information about logline conventions.

Do the characters realize they are in the mind of Anonymous? or is this something revealed at the end of the story?
