Pete's ex-wife and son are kidnapped down in Louisiana while on an archaeological trip. The kidnappers demand that Pete comes to Louisiana in exchange for letting his family go. But when he gets there, it soon becomes apparent that they don't plan to let any of them go.
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."
