This space-age isolation film (that will remind folks of Ryan Reynolds’ 2010 thriller Buried) finds a woman (Mélanie Laurent) waking up in a high-tech cryogenic pod with no idea who she is or how she got there and with less than an hour’s worth of oxygen left to keep her alive. Director Alexandre Aja (Crawl) and novice scripter Christie LeBlanc team up to make a powerful, thoroughly entertaining and perfectly paced claustrophobic pic. Just when you wonder how they’re going to keep up the same plot for more than 90 minutes, it twists and turns into entirely new areas. Laurent is brilliant, and the movie is, too.

4/5 stars
