Nuclear Boy.

The lonely 17-year-old outcast Aike craves attention and finds it online where he conducts dangerous chemistry experiments. Hoping to pull Aike out of his internet bubble, his mother, 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.
