Cynical anti-heroes run a shady pilot business somewhere in South America in “Piu Forte, Ragazzi,” which translates into “All the Way, Boys.” The story is sometimes called “Plane Crazy.” Plata (Terence Hill) and Salud (Bud Spencer) are small-time criminals who ditch planes in order to defraud insurance companies. But, one of their aircraft really does have engine trouble and lands them in the middle of the jungles of South America where plenty of activity is occurring. They encounter some kind of illegal diamond and emerald mine run by Mr. Ears (Rene Kolldehoff), a desperado who happens to be exploiting the natives with his cruel henchmen, underpaying the hard workers and exploiting them. This seems to spark endless melees and standoffs until the ragtag anti-heroes find a flame of integrity to stand up for the helpless while trying to repair their plane to flee the jungle.
