A concrete portal juts from the forest floor, half-swallowed by moss and silence, and Josh Gates steps toward an entrance that hasn't felt human footsteps since the Third Reich fled. The hunt for hidden Nazi treasure moves from legend to terrifying reality as Josh peers into the gaping mouth of a Nazi tunnel buried deep in the Polish earth. The guide's hand-drawn map promised a Nazi bunker sealed by dynamite, but what the flashlight reveals is a nightmare of unstable rock ceilings, rusted support beams, and standing black water that could conceal anything, booby traps, collapsed shafts, or the lost Nazi gold that has haunted treasure hunters for decades.
