NASA opened its astronaut corps to women in the early 1980s, and this film tracks how that happened, narrated by actor Ricardo Montalban. It opens with archival footage from the space program's early decades, when the idea of a woman astronaut was treated as a joke rather than a possibility, then follows the small group who pushed past that skepticism into the selection process. Interviews with former astronauts walk through the physical and psychological screening candidates face, alongside the technical training required before anyone gets near a spacecraft. The film also widens its lens past the astronaut corps itself, pointing to women working in engineering, mission control, and scientific research roles that rarely get camera time. It does not treat the story as finished, noting the limited number of women in leadership positions and the pay gaps still present in the field. Historical footage and firsthand accounts carry most of the runtime, with Montalban's narration mainly threading the timeline together.
