Plot
Geneticist Nathan Sands and his daughter Nicole are hired by the U.S. Navy to create a new weapon; they create an intelligent shark that has the tentacles of an octopus, dubbed S-11, controlling the creature using electromagnetic pulses with a device attached to its head. During one of the test missions, S-11 discards the device before traveling to Mexican waters to find food. Sands and his daughter are then assigned to catch S-11 and travel down to Mexico, where they meet up with fishermen Andy Flynn and Santos, who work for Sands to help capture S-11. Andy, Nicole and Santos track S-11 on Andy's boat as Sands and his men follow in a yacht behind them. Several sightings occur as S-11 kills tourists and locals in the area. Fisherman Pez sends a photo of the creature to a news station, and news reporter Stacy Everheart and her cameraman Bones arrive to find the creature, enlisting Pez's help in the process. Stacy researches Sands and deduces that S-11 is a biological experiment. She, Bones and Pez record it killing a few people on a beach before heading into the ocean on Pez's boat to capture more evidence.

Andy and a group of his diver friends go into a cave to find S-11, although the creature attacks them, killing everybody except Andy. He, Nicole and Santos then encounter Stacy, Bones and Pez, although Pez is killed by S-11 before it runs off. Andy, Nicole and Santos pursue it, resulting in Santos being killed. An enraged Andy radios Sands and tells him he's going to kill S-11 despite his orders. Andy and Nicole track S-11 to the mainland, where it kills a few people before Sands and his men arrive and hold Andy hostage. Nicole reprimands her father for wishing to further the experiments, although S-11 arrives and kills Sands's men before Sands himself is killed saving Nicole. Andy and Nicole encounter Stacy and Bones again, who drive them to a resort which S-11 is attacking. Nicole creates a plan to shoot S-11 with a device that will allow her to blow up a computer chip in its brain using her computer. The group arrives at the resort and Bones soon quits as Stacy attempts to put his life in danger to record S-11. However, S-11 then kills them both. Andy manages to shoot S-11 with the device, and Nicole hacks into the chip before overloading it, causing it to explode and kill S-11. Andy and Nicole reunite, and walk off to safety.
