Safe House plot
In the aftermath of a brutal ambush on the vice president's motorcade, six agents from the Secret Service, CIA, Department of Defense, and Homeland Security are ordered to shelter in a high-security safe house. But when communications are severed and the building is put on lockdown, they discover the real terror lies beneath them: the detonator signal that triggered the citywide attacks has been traced to their location. As armed agents close in and secrets are revealed, distrust spirals into chaos. Every agent possesses secret knowledge and potentially deadly intentions; no one is safe, and no one can be trusted.
