Five thousand years before modern plumbing, the cities of the Indus Valley gave every house its own bathroom and toilet, laid out on a planned grid that this film treats as the first evidence of Indian civilization's reach. From there it moves through a list of claimed firsts: the board game Chaturanga, ancestor of chess, the invention of the numerals one through nine and the concept of zero, which Einstein credited with teaching the world how to count, and yoga and meditation practices that predate most written history. The film spends real time on ancient medicine, describing Sushruta-era plastic surgery used to rebuild noses and ears on people disfigured by punishment or war, along with early cataract removal and smallpox inoculation credited with saving large numbers of lives. Mathematics, astronomy, and metallurgy round out the survey. The film moves briskly across centuries and disciplines, presenting each achievement as a standalone fact rather than building a single argument, closer to an inventory of contributions than a narrative history.
