The story centers around four characters involved in the production of a film in Reggio Calabria. In a dangerous game of secrets and deceit, each one believes they can manipulate their own fate. However, the fragile balance soon shatters, leading to a series of tragic and bloody events.

"Buio come il cuore" is a tale of criminal passion and ambition. As director Marco De Luca puts it: “It’s a modern take on the great classic Hollywood noirs, infused with strong influences from Italian and French noir of the ‘70s and ‘80s, yet told with the rhythm and tension of a contemporary thriller.”
