Four of the best new science graduates have been contracted by the famous billionaire, Felix Strohm, to work for him at an undisclosed location.

They are excited to see Brazil.
They are thrilled to travel up the Amazon River to the laboratory deep in the jungle.
They are inspired to begin groundbreaking work in regenerative medicine.
They are confused when Strohm has them mix animal phyla to create a new form of life.
They are mortified by the aggression and danger the new specimen displays.
They are terrified when the creature reproduces, and an army of killers escape containment.
They are fearful that they will never leave the jungle alive.
