The Invisible Colonies is a speculative documentary film that tells a new history of humanity from an astronomic and microscopic perspective.

In this story, a Scientist from a Martian colony has recurrent dreams of planet Earth that make her feel uprooted and out of context. However, there is no one to turn to, since all inhabitants on Mars have been born and bred in outer space. The information about our planet is fuzzy; the little that is known is that it is not a safe place, and that it´s impossible to go back. In order to find answers to her questions, the Scientist establishes a relationship with microbes; more specifically, cyanobacteria. These ancient organisms were brought to the off-space colonies from Earth to provide nutrients and oxygen for humans. Through dreams and visions, these tiny organisms communicate with the Scientist to tell her stories that question myths and preconceptions of the history of our world. This is when we embark on a journey across time and space: from the vastness of Greenland (where cyanobacteria recount a time in which humans did not roam the Earth) to the agonizing Texcoco Lake in Mexico City (where bacteria were once an important source of food for Aztecs) and back to our current time in the Baltic Sea (where pollution causes toxic blooms that threaten its biodiversity). In this film, we realize that bacteria are heroes and oppressors; friends and foes. However, all life on our planet depends on these microscopic oganisms.
