In prehistoric times, on spring celebration day, two young people meet and fall in love with each other, to the exclusion of all others. They claim their right to monogamy, against the tribe's rules, and are banished. They wander from cave to cave, fighting wild animals by themselves. A hermit teaches them the power of plants and the mystery of impregnation. Later, a child is born but they are soon threatened with drought. Eventually, the saving rain comes back and brings nature back to life, saving this first love.
