MacGyver is sent to retrieve the firing mechanism of a captured
missile being held at the crash site of a downed US fighter plane in Mongolia. As
he infiltrates the camp, MacGyver finds the plane's pilot is alive and being
held captive, presenting an unexpected second objective.
MacGyver is recruited as a last hope when a
mysterious explosion rips through the KIVA Laboratories
complex, a top secret underground research facility, in Bannon, New Mexico
trapping two Nobel candidate scientists. Upon arriving MacGyver finds that he is in a race
against time to rescue the two scientists before the whole complex is flooded with sodium
hydroxide to neutralize an acid leak caused by the explosion.
As MacGyver works his way
through the labyrinth of obstacles (some man made, others damage related) he finds a group
of survivors, one of which, Barbara Spencer, knows where the scientists were when the
explosion occurred and insists on helping MacGyver with the rescue.
As the two continue to work their way towards the trapped scientists, their time is cut
short as the military prepares to fire a missile into the complex to fuse the lower rock
strata and insure the acid cant leak into the aquifer beneath the lab.
