The stock market crash of October 1929 wiped out fortunes in days and helped tip the world into the Great Depression, and this film asks whether it was simply a market failure or something engineered. Descendants of the era's Wall Street insiders sit for interviews, offering family accounts of the men who traded through the crash and, in some cases, profited from it. The film leans into the idea that the collapse was not an accident but a deliberate contraction of credit and confidence orchestrated by a small circle of financiers, a claim it presents through those family recollections rather than through economic data or contemporary documents. There is no reenactment or archival trading-floor footage described here, just the interview material carrying the argument. It sits closer to conspiracy history than conventional economic history, treating the crash as a mystery with suspects rather than a market event with causes.
