Kelvin Doe grew up in Freetown, Sierra Leone, teaching himself electronics by picking through the trash for scrap metal, wire, and old batteries. The film follows him building generators, transmitters, and a full battery pack from discarded parts, then using that homemade equipment to run a community radio station under the name DJ Focus, broadcasting news and music he mixes himself. His talent gets noticed by engineers running an innovation program for young inventors, and at fifteen he becomes the youngest person ever invited into MIT's Visiting Practitioner's Program, flying to Cambridge to tour labs and meet the researchers whose work he had only read about. Interviews with Doe and the people who discovered him fill in how a teenager with no formal training reached that point, and the footage of his makeshift workshop back home does most of the persuading: batteries built from soda cans, transmitters wired from junk, all of it working. It runs short, but it is a complete story with a clear beginning, middle, and payoff.
