The KIVA Laboratories, one of the Sendrex Corporations, was an underground facility located in Bannon, New Mexico. When Dr. Carl Steubens attempted to prevent his work from being used as a doomsday weapon by planting explosives to destroy the facility, the explosion trapped at least 20 people below ground and ruptured a tank of sulfuric acid which threatened to poison the water supply for the southwest. MacGyver was called to the facility in a last chance attempt to stop the acid leak and rescue the survivors.
