Lieutenant Pereira is puzzled by the mysterious murder of a prostitute: it's the second time a woman has been found with her nose cut off, and a special plant known as a "goosefoot" placed beneath her corpse. Suspecting that the killer is basing his actions on the medieval board game of the Oca Brothers, Pereira asks Professor Rinaldi for help. His insight comes too late however: Tea, a young girl on a pilgrimage with a group of young offenders and their minder Leyva, is found murdered.
The Untouchables of Elliot Mouse is a 26 half-hour television animated series loosely inspired by the real life Elliot Ness, and his group of agents colloquially known as The Untouchables, and their investigation into the real life gangster Al Capone, although it does take some liberties with history. The series also parodies the violent atmosphere of Chicago during the Dry Law, as well as the old American films, their heroes and villains.
