Description :
A few days after Christmas, half-sisters Ida and Tuva venture out on a recreational winter dive to the remote Norwegian coast. When a rockslide traps Tuva 33 meters deep underwater, the less-experienced Ida must act quickly to save her sister. Surfacing to call for help, Ida discovers that the rockslide has struck their camp as well, burying their equipment, phones and car keys, and cutting them off completely from outside rescue. As Tuva's air dwindles and a frantic race against time unfolds, Ida is put to the ultimate test of character and resourcefulness. As the stakes rise, a fractured family life is exposed and Ida finds herself fighting for more than just basic survival in this breathlessly cinematic, edge-of-your-seat aquatic thrill ride.
