Peru in the 1930s: While fascism is spreading across Europe, young Maria Reiche (Devrim Lingnau) from Dresden earns a living as a maths teacher in the capital city of Lima. But her true calling awaits further south of the cosmopolitan metropolis, in the Nazca desert. French archaeologist Paul (Guillaume Gallienne) persuades Maria to translate some documents for him, which he hopes will provide clues to an ancient canal system in the area. Instead, in the middle of the dusty solitude, they stumble upon one of the greatest mysteries in human history: gigantic lines and figures scratched into the sand with mathematical precision, which immediately captivate Maria.
Almost obsessed with unravelling the mystery of the geoglyphs, she is prepared to leave her previous life, her love and her work as a teacher behind. Left to her own devices, Maria devotes herself with unwavering dedication to the exploration and preservation of the Nazca Lines... even against the resistance of Peru's powerful elite.
