MacGyver is checking clean water sources in the wilderness and finding signs of pollution. While he checks it out, a hermit, Daniel "Earthquake" Toberman and his dog Buddy watch as a truck travels up a road. He follows them toward a nearby stream where his dog, Buddy, drinks from the stream where they're dumping toxic waste. Earthquake watches in horror as Buddy quickly dies from the contamination. Earthquake goes after the men and attacks one of them, ripping off the man's mask, while the other one grabs a gun. He shoots Earthquake in the leg, giving his comrade time to get back to the truck. MacGyver has found the dead dog and hears the gunshot. As he goes to investigate, the wounded Earthquake sprays the waste at them and they drive off. MacGyver arrives and convinces Earthquake he's on his side and tends to his wound. Earthquake insists he doesn't need help but MacGyver gets through to him and stops the bleeding...Read the full recap
