The Vault

After starting a fire in a nearby warehouse as a diversion, four robbers -- Leah; her sister, Vee; their brother, Michael; Kramer, the safecracker; and Cyrus, the muscle -- initiate a bank robbery. An officer inside the bank tries to call for help on his police radio. Detective Iger, who had just been in the bank hears the call, and decides to check it out. While walking back to check on the bank he hears another, anonymous call on his radio about the robbery.

The robbers find only $70,000 in the vault. Leah wants to leave but Vee and Cyrus demand more money. The assistant manager (James Franco) says he will tell them where $6 million is stored, as long as they don't hurt anyone. He tells them the money is in the basement vault which is a part of the old bank and hands them the key to the access door. Read more on Wikipedia.
