When her reclusive father dies without a will, his washed-up rodeo queen daughter must gather her estranged siblings in order to settle his estate.

It's still not clear what specifically they need to do. What is their goal and what will their main action be?

"...they have one shot of avoiding foreclosure," - what does this mean in practical terms?

Also, "...changing their dubious reputations..." is vague and seems redundant to the plot - you can simply cut it.

Maybe this one drills down a bit more:

I like it. What about this:

When a former rodeo queen and her ex-con?brother inherit their father's struggling farm, they have one?chance to make it a success, ?and one to?turn around their failed lives.

Why not just have both of them inherit the ranch? ?(IOW: there is a will.) ?And they're an "Odd Couple", they never got along a siblings? ?And misfits who are life failures?

Now they must figure out a way to work together as business partners. Because the dramatic problem is not that their father's ranch has been left intestate. ?Rather the dramatic problem is that the father bequeathed them a failing operation, saddled with debt. ?So they can just cash out and sell the operation, take the money and run. They have until October 31, the end of the crop and cattle season, to turn it around or else the bank will foreclose.

The stakes are that it's the last chance for both of them to turn around their failed lives.

fwiw

...and he is the antagonist. There's not a puddle he can't step in, he can't live life straight. He wants to belong but he's just not wired that way.

I want this story to be about sibling who don't know each other and both share their own baggage and screw ups as a result of the relationship (or non-relationship) that they had with their father.

Their situations may be completely different, but they're both without a family, without an anchor, they're screwed up and in search of something to hold onto. This situation is what brings them together.

>>>A down-and-out former rodeo queen is set to inherit her father's lucrative cattle farm, but must employ?her ex-con?older brother?as part of the deal.

1] ?Is that legally possible?
2] If it's a lucrative operation and he's an ex-con , why doesn't he just contest the will so he can get his share rather than be cut out and reduced to a mere employee?
3] Assuming that the premise is plausible legally, it only sets up a situation for a plot. ? So what if ?he's an ex-con? ?If he's a reformed one, ?what's the dramatic problem? What is the plot that follows? ?What becomes?her objective goal?

What do you really want this story to be about?

Is this a comedy or drama? Feels like I was reading the premise to Greedy: ?http://www.imdb.com/title/tt0109936/

The longline needs work but the story has potential. I like the idea of a 'rodeo queen' can see a funny movie involving a group of washed of rodeo drivers who need to have 'one last rodeo'

The will could include a more specific inciting incident that brings the family together (they must win the rodeo championship to get the inheritance for example)

Hope this helps!

UPDATE:

A down-and-out former rodeo queen is set to inherit her father's lucrative cattle farm, but must employ?her ex-con?older brother?as part of the deal.

This sounds like an interesting setup for a drama, but the story needs to have a clear obstacle for her to overcome.
Currently, I'm not sure what the main conflict is going to be.
