A splendid opening with shots of Hong Kong, Colombia, New York and Amsterdam of the drug journey but it ends on the streets of Rome and Fabio Testi the main man. He is in the film the whole time and I assume also his own stunts and he is great and David Hemmings is also fine, probably not doing his own stunts. The last twenty minutes are really wonderful, with planes as well although most of the time it is the drug and mafia crew on the streets. It is good but not anything like as good as Enzo G Castellari's first film of The Big Racket (1976) although it is nice to hear the music of Goblin.
