Tiger Shark Terror

Professional shark diver Eli Martinez and scientist Matthew Smukall plunge into the nighttime world of Tiger Beach to investigate whether shark behavior changes once the sun goes down. After observing different characteristics that make tiger sharks such excellent predators, they'll attempt to outfit the mighty beasts with an advanced camera system, a difficult -and dangerous- task that necessitates putting the sharks into a hypnotic-like state of tonic immobility.
