The story kicks off when a mysterious group organizes "Headshot", a recreation of a video game-inspired deathmatch featuring real people. Eight gamers, wearing custom armor and armed with air rifles, participate in the challenge, equipped with bodycams to broadcast the show live on the ZZIP platform. What appears to be a competition of wits and action, however, becomes a fight for survival, especially when the players discover a vicious killer among them.

January 6, 1980. President of the Sicily Piersanti Mattarella is going to Mass with his family when a young man approaches his car and shoots him in cold blood, killing him. The young Deputy Prosecutor on duty that day is Pietro Grasso, future General Anti-Mafia Prosecutor and President of the Italian Senate. His investigations are continued by Giovanni Falcone, who uncovers dangerous connections between the Mafia, the ruling Christian Democratic Party, neo-fascist terrorists, and secret services.

Antonio is a 30 year old family man, whose life finds an unexpected twist when he's suddenly dumped by his husband, whom he depends both psychologically and economically: he needs to find a new place to stay, a job and a new purpose in life. Antonio finds a room in an apartment owned by Denis and starts to work in a bakery owned by Luca, while attending pastry school. Through this process he discovers that it was wrong of him to give up his independence for the sake of his relationship in the past.

In Palermo, in July '92, a bomb in Via d'Amelio kills Paolo Borsellino and five others, just 57 days after Falcone's death. The mafia massacre begins a judicial process that reveals the weaknesses of the State.
