During the Lehman Brothers minibond fiasco in 2008, many Hong Kong families lost lots of money. It also exposed the helplessness of ordinary people in a financial crisis. Hong Kong director Johnnie To Kei-fung's latest thriller, Life Without Principle, explores how our sense of morality can weaken in such times. In the film, a bank teller, a criminal and a police officer are brought together after they find a bag containing HK$5 million. Teresa (Denise Ho Wan-sze) works in a bank, but fears she is about to lose her job. She has resorted to selling high-risk financial products to unwitting customers. Panther (Lau Ching-wan) is a small-time crook who trades illegal futures . He's determined to make enough cash to post bail for a friend in prison. Inspector Cheung (Taiwanese pop star Richie Jen), meanwhile, faces financial ruin when his wife places a down payment on a house they can't afford. A half-sister who shows up suddenly further threatens his middle-class lifestyle. All three characters are desperate for cash and must grapple with the moral dilemma of what to do with that bag of money. What would you do? Life Without Principle opens tomorrow
