Stowaway (2021) is a sci-fi thriller that follows a tense and gripping scenario aboard a space mission. The film centers on a small crew consisting of a medical officer named Zoe (played by Anna Kendrick), the mission commander Michael (Daniel Dae Kim), and an engineer named David (Toni Collette). They are on a two-year journey to Mars.

The story takes a dramatic turn when they discover an unexpected stowaway, a young man named Michael (Daniel Dae Kim), who has accidentally boarded the spacecraft. His presence complicates the mission significantly, as the crew has limited resources, and their life support systems are designed for only three people. With the oxygen supply dwindling, tensions rise as the crew grapples with ethical dilemmas and survival instincts.

As the situation becomes increasingly desperate, the crew must make difficult decisions that test their morals and teamwork. The film explores themes of sacrifice, humanity, and the lengths people will go to survive in the harsh realities of space travel. Ultimately, Stowaway presents a thought-provoking examination of life, duty, and the consequences of their choices in a confined and hostile environment.
