The Negotiator

Jackson plays Danny Roman, a cop who, anxious to clear himself of false accusations, takes a group of people hostage and requests the presence of a fellow officer from another precinct. Spacey plays Chris Sabian, a hostage specialist, the Negotiator, who comes in to try and defuse the situation and bring Roman in. He is not prepared for what he hears and the city isn't ready for what they do. (official distributor synopsis)
