Dr. Matthew Cooper and many others must run for their lives, but he's among the survivors and joins AERA (emergency agency) boss Harry Stromwell to diagnose the true state of affairs and come up with a daring answer, delivering a sonar bomb by converted space landing capsule into the volcanic crater via a caved-in hole. Hector Janen and his colleagues Glen and Edward are trapped in the control room but attempt an escape trough air vents and the abandoned mine. Green demonstrator Eric and Hank, the plant security guard he mutually pestered, help each-other escape alive. Hector's brother, an outcast ex-con since his single failure as mine guide cost his young nephew's life, now volunteers his expertise to mount a rescue expedition. Oliver's grandson Dylan's hidden cellphone proves vital to get his class's field trip excursion bus located and the kids rescued.
