Anaconda

A poacher hides from an unknown creature in his boat. While it breaks through the boat and attempts to catch the poacher, he commits suicide by shooting himself dead to prevent the beast from killing him.

Meanwhile while shooting a documentary about a long-lost indigenous tribe known as the Shirishamas on the Amazon River, director Terri Flores and members of her crew including cameraman and childhood friend Danny Rich, production manager Denise Kalberg, her boyfriend, sound engineer Gary Dixon, visionary Warren Westridge, anthropologist Professor Steven Cale, and boat skipper Mateo come across stranded Paraguayan snake hunter Paul Serone and help him, believing he knows how to find the tribe they are searching for.
