Darwin, 1878. Maurice Holtze arrives from Germany with a mission from the South Australian government: prove the Top End can grow commercially viable crops. But Holtze discovers something far more extraordinary — the Territory's existing plants are ancient, resilient, and potentially world-changing.
He starts a secret catalogue of species he believes could transform agriculture. He calls it the Seed Vault. When Holtze dies in 1896, the official catalogue goes to Adelaide. The Seed Vault vanishes.
