A murdered teenage girl sacrifices eternal life so she can return as a ghost to protect her younger sister from being her murderer’s next victim.

This sounds like a great mystery...have you thought of her returning as something other than a ghost...as that seems a little on the nose....? Perhaps she takes the form of another person - someone who could create even more conflict? Happy writing!

Thanks for your feedback Tony Edwards and kbfilmworks. I have enjoyed the beginning stages of this project and plan to move on to the outline stage to see if this logline can become a full story. Logline.it is such a valuable support. I will do my part and leave feedback for others to make sure this site continues to grow. Thanks again to you both.

I like this almiiitey -- feels like Ghost meets the Lovely Bones. Regardless of what stage the actual screenplay is at this logline has some compelling elements... certainly enough to get started on.

Good luck.
