Set in the high-stakes world of Wall Street, Margin Call is an entangling thriller involving the key players at an investment firm during one perilous 24-hour period in the early stages of the 2008 financial crisis. When an entry-level analyst unlocks information that could prove to be the downfall of the firm, a roller-coaster ride ensues as decisions both financial and moral catapult the lives of all involved to the brink of disaster.

Kassie, a smart, fun-loving single woman, despite her neurotic best friend Wally's objections, decides it's time to have a baby, even if it means doing it herself, with a little help from a charming sperm donor. But, unbeknownst to her, Kassie's plans go awry because of a last-minute switch that isn't discovered until seven years later, when Wally gets acquainted with Kassie's cute, though slightly neurotic, son.
