Osario and Benedito, two brothers, lead a quiet and isolated life. Gravity doesn’t seem to exist in their cosmos. Objects float around – no up, no down, no points of orientation. The two have never known anything else than this floating in space. We float along and are irritated: is all this lightness just an illusion?

Ricky is a boy from the Ashéninka tribe who lives with his family deep in the Peruvian Amazon Forest. But even here, the children’s favourite pastime is watching videos on their mobile phones. One day, Ricky is faced with the task of overcoming his fears and going hunting for a huge catfish that can only be caught by hook. This is where his journey to adulthood begins.

The towns and villages along the Peruvian section of the Amazon can’t be reached by road. If you can’t afford to take the plane, you travel by cargo boat on the river for days. As a means of transport, the boats are part of an important infrastructure: While the steamships of the “rubber barons” used to travel this route during the brutal rubber boom, cargo boats now bring goods to the communities on the edge of the rain forest.

The observations of the Peruvian brothers Álvaro and Diego Sarmiento and the anthropologist Terje Toomistu are focused entirely on the occurrences on the boat: loading and unloading sugar, chickens, onions, lemonade and building material, the crew, the passengers travelling hammock to hammock on deck, and the people waiting on the banks of the river. The camera never glorifies either the landscape or the work; instead it is always in the midst of things, sometimes even in the way. The journey downstream is accompanied by tales of sinking ships, swimming animals and newfound faith. Observed with such reserve, a lot can still be inferred: about the tough jobs of the dockers, the lives of the women and children who come aboard to sell food, about the influence of the “Israelitas” and how important trading by boat is for the indigenous population of the tributaries.
