On the eve of a $1.2 billion deal, Ethan Blake wakes up with no memory of a wild one-night stand—except that the mystery woman is now blackmailing him. With explicit photos and a 1 p.m. deadline, he interrogates his wife, sister-in-law, CFO, and other female guests, piecing together clues until he pins the bed partner and the videographer. But just as he declares victory, a distorted voice tells him he guessed wrong. The punishment has only begun.
