When an elderly man sues a large bank for foreclosing on him due to a data error, he dies of a heart attack in court, and his daughter then brings a wrongful death suit against the same bank.

Thanks guys, all your comments really got me thinking about this. I think I'm guilty of layering on plot points in an attempt to fix what was really a problem with the expression of my core concept.

Richiev - you hit the nail on the head of what fascinates me about this concept. And you were right on also about me having an initial confusion of my main character which prevented me from ever clarifying this.

It might be more compelling if the mortgage foreclosure drives him to commit suicide instead.

And she didn't lose her father through suicide, she lost her husband. Now it's up close and personal and the stakes are higher: she's being thrown out of her house, facing bankruptcy, has no job and several kids to support.

fwiw

The problem with this logline is, (as read) it switches main characters. It starts as if the father is the main character, then it ends as if the Daughter is the main character.

How about something like this:
-----
"After her father has a fatal heat attack during a viscous court battle, A determined but inexperienced lawyer takes up her dads foreclosure suit against a greedy but powerful banker."
