Episode Overview
After MacGyver witnesses someone dumping toxic waste that's polluting mountain streams, he and Pete enlist a reclusive mountain man nicknamed "Earthquake" to help lead them to the culprit. Things become complicated, though, as Earthquake's flashbacks to his military service in the Vietnam War make him unstable and threaten their case.
