Oxygen 2021

A woman named Elizabeth Hansen awakens in a sealed medical cryogenic unit, only to realize she is trapped inside as the oxygen depletes rapidly. Suffering from memory loss, she struggles to recall her identity and the circumstances that led her there. She finds some support in an advanced AI called M.I.L.O. (Medical Interface Liaison Officer), which unfortunately will not unlock the unit unless provided with an administrator code.

In a desperate attempt to escape, she uses M.I.L.O. to send a distress signal to emergency services, relaying the model and serial number of the cryo unit inscribed on its interior. However, upon contacting the manufacturer, she learns that the unit had been destroyed three years earlier. This unsettling news only adds to her confusion as she desperately searches for answers about her past, sifting through digital pictures and articles until she uncovers her name—Elizabeth Hansen—and her occupation as a cryogenic doctor.

Determined to connect with her loved ones, she accesses her social media and discovers her husband, Léo Ferguson. Eagerly, she calls his number, only to be met with a bewildering response from a woman who seems unaware of her claim. As the oxygen levels continue to plummet, Elizabeth begins hallucinating and attempts to escape the pod, but is met with a shocking electric shock.

Unexpectedly, she receives a call back from the police, but her suspicions about their honesty lead her to disconnect. The earlier unknown woman calls back with devastating news: her husband is dead. Additionally, she provides Elizabeth with the coveted administrator code to unlock the pod, warning her that doing so would lead to her demise. Ignoring the warning, Elizabeth enters the code and finds herself floating in zero gravity.

In a startling revelation, she learns that she has been in hyper-sleep during a 14-light-year mission to a new planet, as humanity faces extinction from a deadly virus—one that tragically claimed her husband, Léo. Overwhelmed by grief, Elizabeth realizes her awakening was the result of a processor overheating. In a race against time and dwindling oxygen, she attempts to redirect the processor’s functions, facing numerous challenges and initial failure due to capacity overload.

As desperation sets in, she contemplates suicide by reopening the pod, but she uncovers that Léo is also in hypersleep aboard the damaged ship, along with nearly 10,000 others. Strikingly, she notices that he is missing a scar he once bore, prompting her to investigate further. Through a video message from an aged version of herself, it is revealed that she is a genetic clone of the original Elizabeth Hansen, bearing implanted memories and personality traits—including those of Léo.

M.I.L.O. initiates a euthanasia protocol given her slim chances of survival, yet Elizabeth’s clone cleverly manages to override this directive and successfully redirects the processor’s functions back, ultimately re-entering hypersleep. The film concludes with a poignant scene of the clones of Léo and Elizabeth on their new home planet, smiling and embracing one another, symbolizing hope beyond despair.
