An elusive gang is terrorizing the city. Criminals are kidnapping one prominent businessman after another and putting collar bombs around their necks. The deadly device is equipped with a camera and radio transmission; it cannot be removed or blocked, and the victim has no chance of escape. If the businessman does not pay the gang the ransom they demand, the blast will blow his body to smithereens. The Chief of Police brings in the best detective, head of the homicide division Lieutenant Troy Brown. To destroy the gang, the lieutenant has to go through trials by fire: experiencing the death of some of his close friends, his own kidnapping and torture, and even wearing the deadly collar. Blast is based on real events.
