A famous singer with everything to lose and the car accident and subsequent trauma threaten her career, then she found her love and wants to make a comeback by doing a hit song again.
Overall this Logline can be simplified to 14 words (as opposed to 23 words) with, “A near-fatal car accident has an aspiring singer downwardly spiral into drugs and depression.” This makes room for the Goal, Stakes and Antagonist, all of which are missing making this a sentence rather than a Logline.
So when editing this ask yourself: What is her goal, what are the stakes and who is the antagonist?
As Lotcher has pointed out, she has no goal, and as she’s only aspiring, she has nothing to lose. Maybe make her a famous singer with everything to lose and the car accident and subsequent trauma threaten her career. Her goal then is to be back on top with a number one song again. Just an idea.
