Somewhere deep in the jungle a chemical corporation dumps tons of toxic waste in a still active volcano. Two nvironmentalists try to expose these illegal ways of getting rid of hugely dangerous waste, but they get caught by the vigilantes working for the company. One of them, the super-hot Maria Giulia Cavalli, manages to escape and she is saved by a snake farmer who lives alone in the jungle. Together they try to bring down the company, but it's too late. Years of chemical poisoning have spawned a deadly monster that is set out to exact revenge on the humans that have unknowingly brought him to life.
