MacGyver is called to a meeting with a former British spy, who has learned of a group of terrorists that will use a new plastic explosive in a vengeful attack on the U.S. army. This explosive can be hidden anywhere. However, before the spy can give MacGyver all the details he is shot. MacGyver flees through a window and is picked up by a boat. The female who owns the boat soon learns that the man she has rescued doesn't have any memory.
MacGyver and Pete are testing a new security system at the Strategic Research Development Administration. MacGyver successfully bypasses the security and meets Dr. Jill Ludlam, the system's designer. She tries to turn off the security system, but it doesn't realize that it was just a test. MacGyver and Dr. Ludlam are then forced to find a way out, as the security system, named Sandy, tries to destroy the "intruders."
