The lonely 17-year-old outcast AIKE (Guus Blanken) craves attention and finds it online where he conducts dangerous chemistry experiments. Hoping to pull Aike out of his internet bubble, his mother (Jelka van Houten), a hardworking nurse, sends him to the scouts to make real friends. When that fails, Aike feels rejected and hurt. To prove himself to the world, he begins his biggest experiment yet: he secretly builds a nuclear breeder reactor in his mother's shed, encouraged by a growing group of internet followers. This success boosts Aike's confidence, and he dares to connect with the boys in his scout group. Aike finally feels accepted! But when the reactor becomes uncontrollable, the catastrophic consequences are unimaginable. NUCLEAR BOY is inspired by true events.
