We are 40,000 BC ... The planet seems to obey the laws of natural selection. Any? No: a valley still holds to evolution!

In a prehistory for operettas that is seemingly doomed never to evolve, a conflicted father and daughter disrupt the Stone Age routine. After a tragic-comedy round-trip to the future, they accidentally bring back an Ikea “bent key”, which will at last trigger Evolution, for better or for worse… Writing, religion, politics… who will be capable of putting an end to these disasters?
