British astronaut Tim Peake spent six years preparing before he ever reached the International Space Station, and this film follows that training rather than the mission itself. It covers his struggle to master technical Russian, a requirement for working aboard the Soyuz and ISS systems, alongside simulated emergency spacewalk rescues designed to drill instinctive responses into astronauts before their lives depend on them. The film also walks through how crews train for rocket launch failures, treating catastrophic malfunction as something to rehearse rather than merely fear. Interviews and archival training footage build a picture of the physical conditioning, technical study, and psychological preparation required before a single minute in orbit, showing the sacrifices asked of astronauts long before liftoff. Rather than dwelling on the spectacle of spaceflight, the documentary stays close to the unglamorous mechanics of readiness: language drills, pool-based spacewalk simulations, and contingency planning that turns disaster into a checklist. It's a portrait of preparation as the real substance of becoming an astronaut.
