Quick recap
Two years later, Riggs and Murtaugh stumble on an illegal shipment of Krugerrand gold coins and end up guarding Leo Getz, a federal witness who never stops talking. Leo explains how the gang launders drug money, and the suspects hide behind South African consul Arjen Rudd, who invokes diplomatic immunity. Riggs falls for Rudd's secretary, Rika, and learns that security agent Vorstedt had a hand in the death of his wife. The hunt runs from Murtaugh's house to the Port of Los Angeles, where the consul's immunity gets revoked.
