With gripping first-hand accounts from banking insiders, regulators and politicians this film tells the story of two recent multi-billion pound trading disasters that rocked the City. It shows that some bankers are still taking reckless risks, five years after the crash that brought the world's economy to its knees. Risk is the engine of growth but reckless risk can have catastrophic consequences, especially in volatile times like the turbulent financial world of today. The film charts the thirty-year effort to manage financial risk through mathematical modelling and shows how this can encourage some traders to behave as if they have mastered risk altogether. With Nobel laureate Daniel Kahneman, former JP Morgan executive Bill Winters and regulator Martin Wheatley.
