The science-fiction novella by V.I. Nemtsov (1907–1993) tells of the great creative work of Soviet people — researchers of the “golden bottom” of the Caspian Sea searching for new offshore oil deposits. The daring and talented petroleum engineers who created offshore drilling platforms and an underwater reconnaissance tank will remain in the memory of readers stirred by the failures and victories of a united, large collective. The author skillfully and truthfully shows the heroic everyday life of ordinary Soviet people who conquer the sea. Nemtsov’s fantastic predictions, essentially true within a decade, came true and became reality.
