Mercury Rising

A cryptographic code called "Mercury" was created by the National Security Agency, so complex that its creators believe no computer on earth can decipher it. Originally created during the Reagan Administration as a test to keep the United States' highest priority secrets under wraps, their assumption is revealed to be false when they receive a message from an autistic savant boy named Simon Lynch (Miko Hughes) who calls a telephone number written in the code, which was secretly published in a puzzle magazine by two of the creators to see if anyone could break it. Colonel Kudrow (Alec Baldwin), perceiving the boy's ability to decipher the code as a liability, seeks to silence Simon; he sends a hit man to murder Simon and his family.
