It’s about a family which is under a curse that makes them die young. But it turns out the curse is actually just the millionaire family patriarch stealing organs from his descendants so he can live longer. And it ends with him locking himself in a panic room because his children and grandchildren form a mob to kill him. But what he doesn’t know is that his emergency supply of immunosuppressants has been removed, so he dies a painful death as his body rejects its foreign parts while they have him trapped.

For legal purposes this is not based on the life of any actual living man with too much money who pumps out kids like it’s his reason to live.
