During a trip to visit some friends, an accident starts a fire in an oil well owned by MacGyver's friends. MacGyver and his buddy then go to fetch dynamite in an abandonned mine at great peril to themselves after they decide the dynamite is the only feasible way the fire can be put out. However, when they use it, the fire only becomes more intense. Can MacGyver and his Hellfire friend survive the incredible heat to put out the fire and save the oil buried underneath the well?

After blowing away a nuclear facility under the control of an aggressive world leader, MacGyver returns home for some peace and quiet, only to find his boss waiting for him. He advises MacGyver that a contract is out on his life and he needs to skip town for awhile.
