Oxygen (French: Oxygène) is a 2021 French-language science fiction psychological thriller film produced and directed by Alexandre Aja and written by Christie LeBlanc.

An American-French co-production, it stars Mélanie Laurent as a woman who awakens trapped in an airtight medical cryogenic unit, with Mathieu Amalric and Malik Zidi in supporting roles.

As the oxygen level continues to fall, Liz begins hallucinating and tries to open the pod, only to receive an electric shock.

Liz uses the code to give herself administrator access, but stops short of opening the pod when the unknown woman begs her to listen.

As time passes and with the oxygen level fading, she prepares for suicide by attempting to open the pod.

The woman she has been speaking to on earth who designed the hypersleep units was herself, but the call disconnects as the spacecraft moves out of communications range.
