Dae-ho then learns of a new form of therapy that allows mental patients to relive important memories through lucid dreams. One of the physicians who administer the therapy is Dae-ho's old friend, So-hyeon. Together, they explore Dae-ho's memories of that fateful day and find a new trail in his lucid dream.
