When two American archaeologists vanish while live-streaming an expedition deep in the jungles of Indonesia’s Halmahera Island, their final footage triggers a classified US intelligence alert dormant since 1945. DIA bioweapons expert Dr. Sara Taylor and CIA operative Alex Ross are sent to investigate. What they uncover is no ordinary ruin, but a sealed WWII-era installation tied to a top-secret Nazi scientific program, and a forbidden series of wartime experiments erased from history. But before Sara and Alex can determine what they’re dealing with, the site is breached by a powerful organization operating beyond the reach of any government. What begins as a mission to rescue two missing Americans quickly becomes a race to stop a weapon hidden at the end of World War II from bringing civilization to its knees.
