Clara Grayson is killed by her husband Julian and her stepmother Isabella, who want her father's fortune and her out of the way. Instead of dying, she wakes three days before the murder, in the same house, with the same smiling faces at breakfast.
She does not run. She quietly copies their affair, their murder plot, and the paperwork meant to strip her father of everything, then freezes the accounts they were counting on. When Julian chases her onto the balcony, she jumps into the pool exactly as their staged accident required, and the FBI is already holding the files. Her father lives, the empire stays in Grayson hands, and the two of them face life behind bars.
