Bond and Natalya travel to Cuba, after Boris is traced to a location within the island's jungles. While flying over the area, the pair are shot down. Onatopp attacks them after they crash land, but Bond kills her during the fight. The pair soon uncover a hidden base beneath a large lake, concealing a satellite dish, and proceed to infiltrate it. Bond is captured while trying to rig explosives to destroy the base, and learns from Trevelyan that he intends to use GoldenEye to devastate London in order to conceal the theft of financial records from the Bank of England, meaning that, in Trevelyan's words, "the United Kingdom will re-enter the Stone Age" and "learn the price of betrayal – inflation adjusted for 1945". While Natalya is captured as well, she manages to hack into the satellite and reprogram it to initiate atmospheric re-entry and thus destroy itself. When Boris loses his cool trying to undo her programming, Bond uses the moment to trigger a grenade, concealed in a pen, to allow him and Natalya to escape.
