The opportunity to finally eclipse Tan pushes Perth to train every chance he gets, even if that means swimming alone at night in the same pool where Ice was found dead. One day, Tan reveals to Perth that Ice committed suicide because she was pregnant. Tan goes on a relentless pursuit to find and take revenge on the culprit. Find out whether love can overcome hatred? Remember no one can hear you scream underwater.
