An object is found that points to the secret of eternal youth so a research team is sent to find the fountain only to find it is protected by a giant snake

Anthropologists deep in the Amazon uncover the remains of a man they come to determine was approximately 300-years old when he died. This leads to a second expedition to discover the reason behind his longevity, but there's a major problem in the form of an Amazonian tribe that guards the proverbial fountain of youth and the giant, five-headed snake they worship.—Scott Foy
