On the tropical island of Manioca, during a MardiGras-like festival, the child of the former president is kidnapped by the thugs of a communistic dictator. A large corporation in Miami finances an expedition to recover...展开the child, and thus hopes to put the democratic nominee back in power. To this end, they send four mercenaries into the jungle, all of whom are masters of warfare. However, while the four mercenaries are fighting their way through the green inferno, new developments are occurring back in Miami. It seems that the corporation has changed its stance, and is now trying to work out a deal with the communistic dictator. This is sadly one of Umberto Lenzi's most neglected films--and for no good reason at all. Perhaps the lack of distribution has contributed to the obscurity of this gem; but, for all serious fans, it remains to be rediscovered. This film is not remarkable insofar as it is extraordinary, but that it so keenly represents the ending of an era. Never again will we see the likes of Antonio Sabato, Ivan Rassimov, Werner Pochath, and Franco Fantasia, all teaming up together in one great film such as this. Besides being well-directed, this movie is augmented by a very nice soundtrack by Stelvio Cipriani, as well as a surpise appearance by Andrea Aureli. Of course, it has its drawbacks as well. For instance, Ivan Rassimov's character is killed off much too soon (the same fate he suffered in Ruggero Deodato's "Atlantis Interceptors"). However, this movie contains some genuinely wonderful scenes that recall all the glory of Lenzi's earlier films. Highly recommended!
