If you say you betrayed him, it sounds as if you were the co-conspirator who turned state's evidence and got off free while he went to jail.

On the other hand, if you were the witness (or victim) whose testimony sent him to jail, then you did not betray him.

Either way, I think the logline would be strengthened if it mentioned the specific crime and your relationship to it.

Katharine:

When I evaluate a logline, the first question I ask is: what's the story hook?? What is the feature that makes the project stand out from similar projects?? What grabs my attention, makes me want to read the script, see the film?

Reviewing the thread of discussion, I found this statement salient:
>>>My reason for going there is because I want to try and see if it?s possible to rebuild a relationship with someone who has been part of your life but whom you really don?t know at all.

So this is the story hook that comes to my mind:? it's about a documentary film maker rebuilding a relationship with someone she betrayed.? Before making further suggestions,? I would like to know a little more about the the nature of the betrayal.? Would you care to elaborate?? Also what is the purpose of your subject revisiting those sites and people?? To make amends?? To apologize?? Or...?
