Watch Oxygen (2021) online

Oxygène, directed by Alexandre Aja, tells the story of Liz (Mélanie Laurent), a young woman who suddenly wakes up inside a cryogenic capsule. She doesn't know how she got there and she doesn't have many memories prior to that moment, but she is in grave danger, because the oxygen is running out and, before that happens, she has to find a way out of the capsule.
She has 90 minutes of oxygen left, so about an hour and a half to try to save herself, but how about her? The only way to survive is to dig into her memory to remember who she is.
