This is one of those obscure ones where an Internet search will leave you none the wiser plot- wise. It opens with Furio (Gustavo Rojo), the "Captain of Iron" of the original title, returning to his village to find it burned to the ground by German usurper Walter von Rauchwitz (Mario Petri), who seems to be on a one-man mission to conquer 16th century Italy and assassinate the pope.
Ignore the misleading title, as what we have here is an old-fashioned Italian swashbuckler about some pillaging mercenaries - I guess committing the "rampage of evil" which we have in the title. Despite lots of appealing attributes, the utterly obscure RAMPAGE OF EVIL fails to be a success due to the almost total lack of action, with all of the swashbuckling being featured in the last fifteen minutes instead of throughout the film.
