Milan's Elite Anti-Terrorism DIGOS Police

Milan's elite anti-terrorism DIGOS police receive a tip that a sleeper cell of Muslim terrorists have received toxic chemicals from Pakistan to make deadly sarin gas.

DIGOS discovers the terrorist cell leader has access to Milan's centers of finance, technology, commerce, and entertainment -- all high profile targets with hundreds of casualties in a terrorist attack.

A team of top DIGOS agents attempts to penetrate the cell and stop them before they act.
