An emotional wreck of a country singer must bring his daughter whom he has never met with him on tour, when her mother goes into rehab for a few weeks.

I can envision a story with , in effect (dare I say it? ), dual protagonists with a dual plot line.

The singer needs to man up and take responsibility for the kid he sired -- but then abandoned. (To pursue his musical career as well as a lifestyle of one night stands, no permanent commitments.) The teenager needs grow up and take responsibility for her actions instead of using her lousy parents as an? excuse for her immature behavior (like doing drugs).

IOW:? a relationship story where each character needs to come to "terms of endearment" with the other in order to grow beyond their character flaws.

But I don't (yet) see that in the various iterations of the premise.

fwiw

Commenting on this version:

After her mother goes into rehab, a girl is all alone and must join her emotionally damaged and estranged country singing father on tour or she'll be placed in foster care.

How do you envision the movie's Act II? Let's say that she joins her father's tour. She is being dragged around the US, attending all his live performances, tolerating his "emotionally damaged and estranged" behaviour. What is she struggling with? Is there a visible goal for her in the story? When does the movie end? Is there a deadline for being cleared of foster care? Is her 18th birthday approaching?

Also: "girl" means a lot of things and a lot of ages. It is very general. Can you give us a hint of her psychological profile?

Here is my version, with random psychological elements (which may be totally irrelevant to your story, but you get the point):

After her mother enters rehab, an introverted teenager must join her egocentric father's singing tour to avoid being placed in foster care.

(I don't think the style of music matters.)
