Viktor lives in a small town in the countryside, where nobody else is openly gay, and he could well do without his brother’s constant jokes. Dina wonders why she is sad when she cannot identify any particular reason for it. Runa has had it with hiding herself and wants to come out, but the principal of her school writes her parents, telling them they need more time to prepare for an openly lesbian student. Joachim’s make-up posts earn him a large following of fans on the Internet, but he also has to deal with hateful comments. The documentary film “Hello World” spends three years following four queer Norwegians at the threshold between childhood and becoming teenagers. Body image, role models, and questions of identity, misunderstanding, love, and disappointment, loneliness, and support from family, friends, and the community. The paths that young people take aren’t always straightforward, but their experiences bring them closer to their desire to live a happy and self-determined life.
