A glimpse into Italy’s longest and most complex investigations into its most savage serial killer to date, The Monster of Florence is a crime drama series that uses the original case to reconstruct the 17-year investigation into the serial killer.
“Horror, to be truly told, must be faced, not avoided,” said director-producer Stefano Sollima about the series. “And a story, to come through with clarity, without embracing a thesis, must begin at the very beginning. To recount it with honesty, respect, and rigor must still carry meaning. Not to solve, not to explain, but simply to remember. A way to remain close to those who were left there, forever in the night.”
Here is everything we know so far about the four-episode event, including the cast, the premiere date, and what to expect.
