In 2009, shortly after the housing market crashed and the markets melted down, the owners of a small community bank in New York City's Chinatown discovered fraud within their loan department. The bank's owners, the Chinese-American Sung family ... reported the fraud to their regulators. But two-and-a-half years later, the bank was accused of mortgage fraud by the Manhattan District Attorney's Office - making Abacus Federal Savings the only U.S. bank to be prosecuted in relation to the financial collapse and the first bank indicted in New York since 1991. Why did Abacus face charges, while the biggest banks on Wall Street all avoided prosecution for fraud? That's the question at the heart of [the new documentary film] Abacus: Small Enough to Jail. Abacus chronicles the Sung family's quest to clear their names, the district attorney's case against the bank - and how 19 of the bank's ex-employees, largely immigrants, were treated by the justice system. When 12 ex-employees of the bank who refused to plead guilty were arraigned, [they were] handcuffed to each other, and in the words of one of their attorneys, "herded like cattle" down courthouse hallways. "Reporters ... were treated to this extraordinary photo opportunity, this almost Stalinist looking chain gang" of Asian Americans, says journalist Matt Taibbi. "I had never seen that in my entire time at the DA's office," says Chanterelle Sung, whose father, Thomas, is the bank's founder. She had worked at the office as a prosecutor for seven years.
