After his sister is raped in a abusive foster home, an Army Ranger must survive a war in order to bring his sisters abusers to justice.

I think this version of your logline is the best version.

Yes, his current mental state is getting in ther way of his accomplishing the tasks and or mission he sets out to do, but is that to much of a clique?

Aha, great suggestion!

I wouldn't get to hung up on the logline. I spent ages working on one, which some say should be done before you write. Personally i think that it's personel choice. In mine, i worked out the jist and will come back to it later.

your story seems to be about bringing justice to the wrong do-ers. The war element may just be a B story, but it is your choice.

You have a guy who has a need (saving his sister) but something is getting in his way (antagonistic force) either his past abbuse or his current mental state are standing in his way. They are his inner deamons, in a sence, he is both antogonist and protaginist.

An Army Ranger needs to put his suicide attempts on hold in order To save his sister from her abbusive foster family.

But the Army Ranger simply has a death wish because of all of the abuse he suffered in the past (essentially he thinks God hates him), but now he realizes that he needs to save his sister so now he redirects..does that make sense? Im having a little trouble figuring out what items should go into the logline if there are so many options to choose from...in terms of what has happened to the ranger during his life.

Lew, thanks for the feedback :)
