This documentary summarizes every problem that our planet and humanity undergoes and emphasizes that it is a consequence of the actual obsolete social political and economic system. A system that is based on consumerism, waste, scarcity, ownership, exploitation, competition, social inequality and corruption. This movie suggests an alternative, a system based on scientific method and knowledge. It is efficient and sustainable, it reassures abundance, and eliminates the necessity of money. The goal is to upgrade the society to be consistent with the technological era. The system we are talking about is Resource-Based Economics. The first part of the documentary is a quick glimpse through the problems our planet and us are facing and all the solutions available in order to achieve a necessary change. The conclusion is that the ones who are guilty of the actual state of things are the same who are preventing a change to happen and obstruct the solutions.
