The Mafia presence in Manehattan is well-known by many ponies, especially by the MPD. Their top investigator, Daring Do, has been searching for one of the most notorious crime bosses known as the "Photo Finisher", who currently heads the Mafia in Manehattan. Two of the best contract killers, Vinyl and Octavia, get dragged into this marehunt after a chance meeting with Inspector Do, and are faced with an ultimatum: rot in prison for the rest of their lives, or band together with the Manehattan Police in order to bring down one of the most twisted ponies in Manehattan's crime-filled history.
