Stowaway

Stowaway is a 2021 science fiction thriller drama film directed by Joe Penna, who co-wrote the screenplay with Ryan Morrison. It stars Anna Kendrick, Daniel Dae Kim, Shamier Anderson and Toni Collette. A co-production of the United States and Germany, it premiered on Netflix in select countries on April 22, 2021. Plot Mission Commander Marina Barnett, biologist David Kim, and medical researcher Zoe Levenson lift off aboard MTS-42, a two-year mission to Mars. Once underway, the upper stage of their launch vehicle is connected by 450-meter tethers to the ship's main hull, acting as a counterweight for inertia-based artificial gravity. Shortly after takeoff, Barnett discovers launch support engineer Michael Adams, an accidental stowaway, unconscious between two modules, entangled with a device that scrubs carbon dioxide from the air on the ship. As he falls, the device is inadvertently destroyed. The crew is forced to use emergency lithium hydroxide canisters to scrub from the air. Unfortunately, the canisters cannot sustain the extra load. Barnett orders David to immediately cultivate his algae experiment on the ship, rather than at the Martian colony as planned. Only half of the algae survive, providing just enough oxygen for a third crew member. Without another oxygen supply, the crew of four will asphyxiate weeks before reaching Mars.
