When the UK government ignores growing evidence of climate breakdown, three British scientists take matters into their own hands. Facing arrest, criminal records, and damage to their professional reputations, they turn to civil disobedience to warn the public. The film follows their journey, revealing the tension between scientific credibility and activism. Scientists, typically seen as detached and analytical, now take to the streets in an urgent call for action. Over three years, the film documents their increasing role in climate protests, exploring how their shift from research to direct action challenges public perceptions and the ethics of their profession.
