A filmmaker’s conversations with his young son about the different ways in which they experience time leads to a deeper reflection of what time actually is, attempts to control it, and how it shapes human experience. . From the physicists who look after the atomic clocks that run the modern world, to the daily ways in which average people contend with time, to the eternal relationship between time and power, the film explores the tension between objective and subjective time: intimate, philosophical, poetic, political and scientific.
