This crime thriller tells the story of an undercover cop (Fabio Testi) who has to "play" a drug dealer so that the real dealers accept him as a member of their syndicate and he can come close to the big men at the top of the syndicate. As it is the problem with many genre films of its decade, the depiction of the drug dealers, their environments and the investigating methods of the undercover cop looks clichéd and hilariously out of date. Except for that, this is a highly entertaining, action packed film.

Fabio Testi never looks like a real drug dealer, but who cares, his acting is solid as ever. David Hemmings as the police inspector who knows about Testi's true identity brings English flair to the role with his sometimes almost exaggerated British accent. The supporting cast consists of many faces familiar from other Italian genre outings (e.g. the ruthless syndicate killer in Lucio Fulci's "Luca il Contrabbandiere" from 1981, also starring Testi in the lead role), and the score by the (at that time) Argento regulars "Goblin" just rocks. There are some quite original action sequences, especially the climax, in which director Enzo Girolami delivers a plane chase for once instead of a car chase (and this plane chase looks daring sometimes). Because the simple plot always pushes the action forward, the movie never becomes boring and delivers.

Certainly not Enzo Girolami's best film (his "La Polizia Incrimina, la Legge Assolve" is probably the best Italian crime film ever made), mainly because the story is never really convincing, but it's fast paced and will please every fan of Italian crime thrillers.
