The city needs saviours and only masked vigilantes will answer the call.

In Part 2, Rorschach contacts Nite Owl to get his help in solving the case of a missing girl, Violet Greene. Along the way Rorschach uncovers that a woman from his past is involved with the disappearance, leading to a conflict of interest between the partners.
