The Macocha Abyss is the biggest abyss of its kind in the Czech Republic and even in the Central Europe. It depth of 138m was a great challenge for both of the B.A.S.E. jumpers, Martin Trdla and Robin Kaleta. There was more than the jump which requires technical proficiency, there was the aim to show how easy and difficult it is to get prepared. At first sight it seems all the legal restrictions were broken for the humble thirst for fame and popularity, to be seen in a film. However, the jumpers wanted to point at absurdity of some rules and obstructions. The feature connecting the document to other ones by Jumps, o.s., the wish to lead nonspecialist audience through the backgrounds of B.A.S.E. While filming the unconventional documentary there were no fatal or other injuries to any members of the team, no harm to property private or state, and all the team behaved extremely carefully to protect the nature.
