While a timid heiress plans to overthrow her abusive mother, a disenfranchised heir to the wealthiest family in the U.S struggles with his responsibility after his grandfather puts his inheritance up for grabs in his will.

I think the logline is to long for me, I'm trying to see who the antagonist is here and who the protagonist is and the death steaks but I get lost half way through, then It just leaves me blank at the end wondering what? Can you change the words to make them more appealing,
An insecure son plans to over through his abusive mother, an excluded heir to the wealthiest family in the U.S struggles with his responsibility after his grandfather puts his inheritance up for grabs in his will.
But I'm still not sure what the death stakes are here?
