The BBFC 18 version of this Fulci classic has been heavily censored. There are not only several plot scenes missing but nearly all violent scenes were altered making this version completely useless.
The film was resubmitted to the BBFC in 2014 and all previous cuts were waived so the current UK DVD released by Shameless is completely uncut.
Someone is muscling in on the two brothers' cigarette smuggling into Italy at Naples. The police is tipped off, then Mickey's stable burns down, then the killing etc. starts. Luca responds.
