About the title
Diver sisters Drew and May go on their traditional joint dive in a new location, a remote, semi-wild corner, with no idea what they're about to face. A rockslide traps May in a deadly underwater trap, and time is running out: oxygen is nearly gone, panic is rising... Drew can only rely on herself and is forced to make fateful decisions to try to save her sister at any cost. At the depths of fear, only hope remains.
