Oxygen

“No escape. No memory. 90 min to live.”

A woman comes to inside a sealed medical cryogenic unit, wrapped in cables, with no memory of her name or how she got there. Alexandre Aja keeps the whole film inside that chamber with Liz Hansen (Mélanie Laurent) and the voice of the unit's assistant, M.I.L.O (Mathieu Amalric), while the oxygen level on the display counts down. Her hands pull at the lid and the wires, and the number on the screen keeps dropping.
