Black Ops.

BLACK OPS travels the world to take viewers along on top secret special ops missions. The series reveals how elite special operations units in different countries carry out their high-risk/zero-recognition assignments and shares the inside story of some of the most dramatic military actions in recent history. When 40 Chechen terrorists armed with guns and bombs hold 800 theater-goers hostage, it's up to Russia's elite anti-terrorist force, Spetsnaz group "Alpha," to get the hostages out alive. Negotiation is not an option, and a siege would set off the explosives. The only way to save the hostages' lives is to use an untested top-secret knock-out gas.
