Weapons of Death (Italian: Napoli spara!, also known as Naples Shoots) is a poliziottesco film directed by Mario Caiano in 1977.

[2] It is spin-off from the Commissioner Betti Trilogy as the character of Gennarino (still played by Massimo Deda) returns from the film Violent Naples.

[3][page needed] In Naples, the young commissioner Antonio Belli, despite the good will and support of a special team, is unable to arrest the bandit Salvatore Santoro, sure of the protection of his godfather Don Alfredo Criscuolo, the Camorra boss who manages all the drug trade in the city.

Not even the attempt to turn a rival gang against him leads to better results, and Santoro and his men continue to carry out several hits and spread terror in the city.

Finally captured and put in prison, Santoro escapes thanks to the intervention of the elderly boss.
