A man wakes up in a native village and can't remember how he got there. As he is aided back to health through rest and the topless magic of a young girl, the village soon comes under attack by a helicopter which drives the man to flee into the jungle. After falling over a waterfall, he washes up to shore and is greeted by someone wanting to help him. But before he can explain himself he is snatched up by some bandits and brought back deep into the Amazon to guide them to "The City of Emerald". The adventure is just beginning as the group try and survive through piranha attacks, native battles, smashing spiders and a run in with other psychotic treasure hunters in their quest for riches.
