Zombi 3 is a 1988 Italian horror film directed by Lucio Fulci and Bruno Mattei and starring Deran Sarafian, Beatrice Ring, and Ottaviano Dell'acqua. The film is an in-name-only sequel to Fulci's Zombi 2, and the only official sequel to Zombi 2. The film is about a group of scientists at a top-secret research facility who are working on a biological weapon called Death One, which mutates and kills the living creatures and reanimates the dead. The weapon is leaked out of the facility, which leads to a spread of infection among soldiers and tourists in the area.
