In 1983, when Sally Ride became the first American woman in space, NASA asked if 100 tampons would be enough to last a week. ‘That’s probably not quite the right amount,’ she replied with dry humor. Sally presents her story—from the public image of the steadfast astronaut to her private love for Tam O’Shaughnessy. For the first time, Tam opens up about their 27-year relationship. A moving film about courage, identity, and the extraordinary madness it takes to make history.
