Episode 70 of "MacGyver"
s04e06 The Survivors

MacGyver, on assignment for the Phoenix Foundation to test current field operatives to see if they are still in shape, has quickly grown distressed at the fact that he just washed out one of the supposed "best" field operatives. When he asks Pete to take him off the job, Pete agrees- after he qualifies him. The next day, MacGyver and Pete head out into the wilderness to begin the survival testing course- with Pete as the student and MacGyver the instructor. Soon after Pete completes an obstacle course, which other students had named "MacGyver Land" the two find an airplane with two pilots who had only recently died. MacGyver and Pete soon realize the plane was on a reconnaissance mission for the Drug Enforcement Administration (DEA) and that it was shot down by a heat seeking missile. Through the use of battery acid and the juice of an orange, MacGyver is able to briefly view the pictures the DEA plane took before being shot down- a sea plane on a lake and two men, presumably drug smugglers, with a handheld missile launcher. MacGyver then determines the only lake large enough for a sea plane to land in is the nearby Crystal Lake. MacGyver then makes Pete aware of the fact that they cannot call for help and it is a three day hike out of the wilderness. They soon decide to head for Crystal Lake to try and stop the drug smugglers. Meanwhile, the smugglers have just unloaded another shipment of cocaine into a secret cave and have headed back to their "base" ship in the ocean for another shipment. While they are gone, MacGyver and Pete arrive and have a look around the cave. Not surprisingly, the smugglers soon show up while MacGyver and Pete are still inside. Eventually, the two are caught and a grenade is tossed in their direction, which blockades them in a section of the cave with no escape route- with the exception of a hole that is thirty feet above them. MacGyver figures a way to reach the hole, despite Pete saying it cannot be done. MacGyver proves him wrong by reaching the top fairly easily. Now it's time for Pete- who's a little out of shape to say the least- to do the same. After much frustration, Pete makes it to the top. MacGyver climbs out of the top of the cave via a pick hammer- but doesn't realize that the smugglers have heard the sound of the hammer from their position. While one of them investigates the strange sound, MacGyver tosses Pete the hammer back. In his haste, Pete misses the hammer and the rope attached to it. Meanwhile, the smuggler has assumed the sound was nothing and has gone back to the sea plane to continue his unloading. MacGyver is able to help Pete out of the cave- barely- but there is another problem now. Can MacGyver and Pete stop the cocaine distributors before their buyers arrive to take it all away? Will Pete's seemingly lacking physical fitness spell disaster for both himself and MacGyver...?
