An oddball couple turns a simple break up conversation into a fatal encounter when ulterior motives for the split start surfacing.
Could you specify who of the couple will be the main point of view character? In other words is there a main character in the story?
If not then it will be very similar to War Of The Roses and as such will likely need an external character’s point of view to tell the story through like the Dany DeVito character.
The Ulterior motives description is too vague to be useful in a logline, why not specify exactly what each of them wants so it is clear what their actions will be throughout the story?
Hope this helps.
This logline is the sort of logline that gets on imdb.com or in the TV listings.
But I see this website as more about writing loglines that act as a tool for helping me nail my story structure, the throughline, the main character, what they want, who or what is stopping them,their arc/change.
When you nail a logline in this way, you have the structure that will ensure you stay on track.
There was a logline on this site that was 69 words and no clear throughline, it was all over the place but that’s why you rewrite it over and over until it’s the best it can be BEFORE you even write the actual first draft it. That’s the approach I prefer to work to be honest.
I hope this makes sense.
