An anti-terror convention in Washington D.C. is rocked by a real-life hijacker -- and Frank Hardy's girlfriend, Callie Shaw, is among the hostages. When Callie appears on the TV news she sends the Hardy's a coded message. Trouble is, the government doesn't believe them.

Agent O'Neill orders Frank and Joe off the case, forcing them to try a rescue on their own. Suddenly the brother sleuths are running from the law, straight into a terrorist trap -- while Callie watches her life tick away.
