In a world where passive-aggression is an art form, a terminally polite man finally reaches his breaking point. Daniel Radcliffe stars as Henry, a mild-mannered office worker whose life is a symphony of unreasonable demands and subtle disrespect from colleagues, neighbors, and even his own family. His journey begins when a seemingly trivial inconvenience sparks a quiet revolution within him, leading to the adoption of a radical new personal philosophy. As Henry begins to experiment with setting firm, if bluntly worded, boundaries, his small acts of defiance create chaotic and unexpected ripple effects through every facet of his meticulously ordered life. This darkly comedic exploration of modern social anxiety blends cringe-worthy humor with moments of genuine catharsis, asking just how far a person can go to reclaim their peace before everything falls apart. Henry must navigate the hilarious and often disastrous consequences of his newfound assertiveness, discovering that telling the world to back off is far more complicated than it seems.
