An old bus makes its way through the dangerous roads of Colombia. On board, Franz Florez introduces the population to his snakes. When armed men start filling the streets, Franz faces up to danger, an anaconda on his shoulders. A series of tests await him: guerilleros and coca growers in dires straights, an angry ecologist grandfather, a blind local man who possesses many secrets... Meanwhile, Franz's wife is out of telephone range, and perhaps has gone forever. At the end of his adventure, he has a strange message to deliver: civil war will protect the country's ancient forests.
In the heart of an astounding, inaccessible Colombia, the Snake Man sees his life slowly turn into a strange tale of initiation.
