A series of peculiar murder cases imitating the underground manga Nekros brings Kaye, the famous manga artist hiding a nasty past, and Phat, the righteous detective investigating these murders, together. The two may have different outlooks on justice, but the more they unearth the case, the more they find out that their lives are both involved in the same tragedy. When the truth comes out, both Kaye and Phat must face their painful past and make a choice between revenge and justice. This is the beginning of a friendship, trust, man's fight against the dark side of their own mind, and a grand puzzle waiting to be solved.
