: During a winter dive in Northern Norway, a rockslide pins Tuva's leg at a depth of 30 meters. Her sister Ida, the less experienced diver, must navigate a series of logistical and environmental obstacles to save her before their oxygen runs out.
: While a fictional narrative, the film touches on the physiological dangers of deep diving, including the "bends" (decompression sickness), nitrogen narcosis, and oxygen toxicity. Critical Reception
The 2020 survival thriller follows two sisters, Ida and Tuva, whose annual winter dive in the remote Norwegian wilderness turns into a fight for survival after a rockfall traps one of them on the ocean floor.
: Shot by Anna Patarakina, the film utilizes a "steely gray and blue" palette to emphasize the freezing Arctic environment. Underwater sequences, handled by DP Eric Börjeson, use tight framing to create a sense of claustrophobia and disorientation.
: The story blends "family therapy with acute disaster," exploring the strained relationship between the sisters as they are forced into a situation of mutual reliance.
Directed by Joachim Hedén, the film is noted for its high-stakes tension and brutal, isolated setting. Core Feature Elements
Critics have highlighted the film's "nerve-splintering" suspense and its ability to maintain a cliffhanging pace despite its limited cast and singular location. However, some members of the diving community have criticized certain technical inaccuracies or the "foolhardy" nature of the dive attempted by the characters.
