In the year 2070, mankind faces a life threatening crisis due to huge earthquakes and volcanic eruptions. Korea is in a state of anarchy and Busan is swarming with refugees. Young street dealer Ha-jin has the ability to communicate with whales – a fact she keeps hidden from everyone. One day, a onearmed woman named Baek Sang-won asks Ha-jin to join her in the gules whale hunt. Painful memories lead Ha-jin to turn down the offer initially, but she eventually ends up joining Baek. As she makes friends on the ship, she grows curious about the gules whale and learns that every crew member has a sad gules story. The madness in the crews’ eyes as they try to kill the gules brings Ha-jin’s trauma to the forefront of her mind – and she experiences her own madness. (Source: Korean Film Biz Zone)
