Atrapada en las profundidades

Survival film from Sweden. Two sisters who are reunited after a long time, go together for diving like they used to when they were kids. Only while they're at the bottom of the sea, rocks fall and the younger sister gets trapped on the bottom. The older one doesn't have her sister's experience but with her guidance she tries to do everything to save her. Constant challenges and setbacks and constant effort against time as oxygen runs out. Will they both make it out of the frozen seabed alive? A pretty good and serious overall survival film from Scandinavia, with snowy landscapes and cold seabed, quite realistic and with very good acting, suspense throughout the film and combined with its short duration does not become boring at all. Pretty good effort from the north. Recommended.
