A happy Swedish family vacations in an upscale ski resort in the French Alps. Things take a bitter turn when a sudden avalanche threatens to flatten mom, dad and the kids. This scary, snowy disaster peters out before anyone is injured, but dad reveals his true nature (maybe) by ditching the family and running away like a coward. Mom (Lisa Loven Kongsli) is quietly horrified, dad (Johannes Kuhnke) is secretly mortified, and the kids are sullenly terrified. Filmmaker Ruben Östlund uses this simple premise/discussion-starter to perform an ice-cold autopsy on modern marriage, family dynamics and gender roles. In English, Swedish and French with English subtitles.118 minutes R.
