Following the story of three California condors - Shadow, Amigo and Cosmo - we discover the destiny of this miraculously saved species. The California condor was reintroduced into the wild just twenty years ago and has managed to repopulate its former territories. Even so, our heroes now face new threats which cast a shadow over their success story. While scientists have found solutions for a syndrome affecting Shadow, the one that is endangering Amigo and Cosmo is still a mystery.
