Blair Kennedy, a top Manhattan lawyer, drafts a strict prenuptial agreement for her wealthy fiancé Alexander Wentworth. Moments before signing, she learns he hid $300 million in debt through shell companies. Instead of confronting him, she discreetly adds a clause: any undisclosed debt over $1 million belongs solely to the debtor. Alexander signs without careful reading. When his empire collapses, he tries to force Blair to share the debt burden, yet the clause fully protects her. He loses everything, and she walks away. Blair leaves her elite firm and opens a small Brooklyn practice called “She Signs,” helping ordinary women understand prenuptial agreements. She guides many clients to spot unfair terms and defend their rights. Alexander files for bankruptcy and remarries later. Blair never remarries but finds fulfillment in her work.
