Harry and Jack owe money to O''Brian, a violent gang boss. They''ve spent his money, so have to hide in Amsterdam. Jack falls for a beautiful prostitute. Harry returns when told of O''Brian''s death at the hands of the Rossi crime family. Harry and Terry (his brother) meet Jack on his return. Whilst at a brothel they''re faced by one of O''Brian''s gang. Terry kills three of the Rossi gang. Whilst on remand, Terry is killed by the Rossi''s. That starts a vendetta, "Vengeance is Ours" is the mantra as Harry an Jack take revenge.
