Blair Kennedy, a top Manhattan lawyer, drafts her own prenuptial agreement with wealthy fiancé Alexander Wentworth, discovering he has hidden $300 million in debt. She adds a clause stating that any undisclosed debt over $1 million is solely the debtor’s responsibility, and Alexander signs without reading carefully. When his empire collapses, he tries to force Blair to share the burden, but the clause protects her. Blair walks away and opens a small Brooklyn practice called “She Signs,” helping women understand prenuptial agreements. She guides clients through unfair contracts, teaching them to protect themselves. Meanwhile, Alexander files for bankruptcy and remarries in Chicago. Blair never marries again but finds fulfillment in her work, realizing true protection lies in understanding what you’re signing and trusting those who deserve it.
