Zodiac.

A serial killer targets a rich family that owns a banking group and kills them through an astrological ritual scheme. He leaves behind mysterious messages from Nostradamus, which he signs with the symbol of the zodiac. It will be the illegitimate daughter of the head of the family, Ester -- with the help of a skeptical commissioner -- to unravel the mystery, untangling herself in a dense web of intrigues that hide behind the powerful and respectable family.
