I really hate these things ...

'A young woman’s violent nightmares slowly reveal the truth of her mother’s murder, and the man with the most to lose, her father, uses his Washington influence to hunt her down.'

Okay.

What is it that you need help with?

??

I'm assuming that's your logline and you're just wanting us to crtique it.

So I think it's good but I think the part "and the man with the most to lose, her father" reveals a bit too much. You clould almost go with just "A young woman’s violent nightmares slowly reveal the truth of her mother’s murder"

Is the story more about the young woman with recurring nightmares, or more focused on her father and his efforts to hunt the killer? Or do they work together?

Who is the main character?

I think ada's comment is most important. Right now it reads as though there are two separate stories that change halfway. Once you decide whose story it is go from there. DO keep in the father detail even if its the girl's story. Loglines aren't intended to cause mystery. Not really a marketing ploy, but a boiled down version of the story. Ask yourself "why do we care?" when you write it. That will help you decipher key plot points from unnecessary words.
