Born on September 11, 1985, Kevin Stillwater has lost one family member after another on his birthday, including both of his parents at the Pentagon in 2001. As a result, Kevin grew up troubled and afraid his birthday would ultimately lead to the extinction of his entire family. Although born into wealth, Jeremiah Flint follows his uncle Solomon into a career in law enforcement. While working for the Kansas Bureau of Investigation, he befriends Kevin and enlists the young man's computer hacking skills to find his nephew, Ivan, who is missing in the foster care system. As Kevin's 21st birthday approaches, Jeremiah fights for his life, Ivan is kidnapped, and Kevin's last remaining brother is shot down in a helicopter. On September 11, 2006, the race is on to save Jeremiah, rescue Ivan, and stop Kevin from trying to end the family curse by committing suicide.
