Humanity finally ignited nuclear fusion — the same reaction that powers the Sun. But despite headlines claiming unlimited clean energy is near, the truth is far more complicated. Inside massive fusion reactors, scientists achieved a historic breakthrough… yet the machine needed to turn fusion into a real power source still doesn’t exist.

In this documentary, we explore the science behind fusion ignition, the impossible engineering challenges, trillion-dollar reactor projects, and why the future of energy may still be decades away. Is fusion truly the answer to the global energy crisis — or are we witnessing the world’s most expensive experiment?
