Yeri and Ah-Jin, a niece and aunt, are strangers to each other, as they spend a fractured summer together on a remote North Sea island. Yeri is isolated at school and emotionally neglected at home. Ah-Jin lives in self-imposed exile, working as a caregiver while carrying the physical and psychological wounds of her past. Over the course of the vacation, they learn to understand and respect each other, and eventually accept who they are.

At a prep school, a secret horror begins to unfold as the students begin to die.

Late at night, Woo-hyuk working on writing poems is visited by his ex-girlfriend, Nari. He tries to mellow her out only to find that they exchange misunderstandable words with each other. Recalling their travel to the island "JeBu", they finally find something in common to share. Now Nari asks him to travel to somewhere with her.
