Three stories of accidents that changed daily life, told with narration, archival images, and historical reenactment. An American tea merchant trying to cut shipping costs by packing samples in small silk bags accidentally invents the teabag, changing how the world brews tea. A political prank aimed at humiliating a small-town council instead backfires and puts the first female mayor in United States history into office. And in the malaria-plagued outposts of the British Empire, a soldier's desperate attempt to mask the bitter taste of quinine water produces the gin and tonic, now one of the world's most ordered cocktails. Each segment traces the same pattern: an ordinary problem, a small workaround, and a consequence nobody involved could have predicted. The film moves briskly between the three cases rather than dwelling on any one, using them to make a broader point about how much of everyday culture, from a cup of tea to a bar order, traces back to nobody planning for it at all.
