Deep in the Democratic Republic of the Congo, an illegal diamond mining operation is interrupted by the presence of a giant 1,500-foot crocodile. Meanwhile, on the Atlantic Ocean, the USS Gibson is attacked and sunk by the Megalodon from the first film. Lt. Terry McCormick (Jaleel White), who was experimenting with a sonic shark-repelling device, is the sole survivor of the attack. Back in DR Congo, an English hunter named Nigel Putnam (Gary Stretch) successfully captures the giant crocodile when it attempts to eat him and he injects his tranquilizer darts in its mouth. He then has the crocodile delivered to a shipping yard for his friends to load it in a cargo ship.
In Los Angeles, California, McCormick is being interrogated by NOAA Special Agent Hutchinson (Sarah Lieving) for the USS Gibson incident. He feels responsible for the sinking, suggesting that his sonic device lured in the Megalodon. Because of this, he offers to help Hutchinson hunt down the Megalodon with his invention. Meanwhile, a cargo ship is carrying the tranquilized crocodile on the Atlantic Ocean 400 miles south of Florida. It is revealed that the ship is also carrying the crocodile's eggs as well. Then, without warning, the ship is attacked by the Megalodon, waking up the crocodile from its sleep. Putnam jumps overboard before the ship is destroyed in the ensuing battle.
Aboard the aircraft carrier USS Lexington, McCormick is introduced to Admiral Calvin (Robert Picardo), who informs him that his elite crew has only one objective: to hunt down and destroy the Megalodon. McCormick is given a room aboard the carrier with the most advanced tracking equipment. Hutchinson is sent to a remote island to meet and interrogate Putnam, who had just washed up ashore following the cargo ship incident. Hutchinson is shocked when Putnam informs her of the crocodile he captured, as her team was only aware of the Megalodon. She then has him handcuffed and brought back to the carrier. Once there, the crew discover the appearance of eggs on another island. Adm. Calvin assigns McCormick to accompany Hutchinson and Putnam and capture an egg. Upon arriving on the island, they discover that the eggs are laid by the shoreline and are about to hatch. When the fin of the Megalodon is seen nearby, Hutchinson orders the Lexington to launch a missile strike on the island. As the team leaves the island, the Megalodon swallows the eggs, angering the crocodile while a squadron of F-18 Hornets fire their missiles at a cave holding more eggs. As the crocodile invades Miami and heads toward Orlando, McCormick suggests the use of an arc flash powered by the nearby Turkey Point Nuclear Generating Station to ward it off. The gamble works, as the arc flash sends the crocodile back into the sea.
Back aboard the Lexington, Putnam suggests to dissect a crocodile egg to find its Achilles' heel; the team is informed that one egg is aboard the submarine USS Invincible and two are being transported by Black Hawk helicopters. They also discover that the Megalodon is attracted to the eggs, as it has devoured the Invincible and the Black Hawks transporting them. As no cage or trap is big enough to capture both creatures, Putnam suggests to lure both the Megaladon and crocodile into the Panama Canal, much to McCormick's disapproval. The submarine USS Argonaut is sent to the wreckage of the cargo ship to retrieve some crocodile eggs. The retrieval mission is a success, and the eggs are dropped into the Panama Canal. Instinctively, both the Megalodon and the crocodile arrive at the canal, where they battle each other while being attacked by a missile strike by a squadron of Hornets. The fight causes a tidal wave that destroys the entire Panama Canal as both creatures continue to bite each other.
It is later on revealed that the crocodile has adapted itself to lay more eggs during the time the Megalodon devoured the earlier batches. Hundreds more eggs have been laid all over the American coastline and are hatching. While crocodile hatchlings are attacking the Santa Monica, pier, the nuclear submarine USS Carter is in pursuit of the two giant creatures, which are headed toward Hawaii. The Carter fires a nuclear torpedo at the creatures, but misses before she is swallowed by the Megalodon. This results in the Megalodon becoming an even bigger threat, as it has a nuclear reactor inside it. As the crocodile invades Hawaii, it causes the helicopter carrying McCormick, Putnam and Hutchinson to crash. With Hutchinson unconscious, McCormick and Putnam leave her and take a raft to drop McCormick's sonic emitter in hopes of triggering an undersea volcanic explosion. The emitter lures both creatures and hundreds of crocodile hatchlings. The duo then head back to shore before the emitter causes an undersea volcano to erupt, engulfing all of the creatures in molten lava. McCormick and Putnam are then picked up by Hutchinson, who has recovered and reactivated her helicopter. The trio fly home as the crew of the Lexington celebrate with Adm.
After the credits, Nigel meets up with his partner in the DR Congo and mentions a giant lizard in Japan. He asks him if he's up for it, and his partner says "On one condition - no more boats." They shake hands and head off on another adventure.

Connections with other Asylum titles
The film makes numerous references to Mega Shark Versus Giant Octopus, such as an autographed photo of singer/songwriter/actress Debbie Gibson and the Japanese poster of the first film. In addition, scenes of people panicking are taken from the film Megafault.
To promote the film, The Asylum participated in a competition to make the next Doritos commercial for Super Bowl XLV. In the commercial, the Megalodon attacks a naval fleet while Capt. Smalls (Michael Gaglio) asks if anything will satisfy its hunger. Then he hears a crunch and sees the janitor eating a bag of Doritos. In the next scene, a helicopter carries a giant Dorito chip over the ocean. The Megalodon jumps and eats the chip before fleeing from the scene as the whole crew celebrate.
Dread Central gave the film a scathing review, giving it a score of "1 Megacraposaurus" out of 5. The review commented that "movies like this always tread a fine line between anything-goes fun and merely insulting your intelligence, and this time The Asylum may have finally jumped the mega shark." Felix Vasquez, Jr. of Cinema Crazed gave the film one star, calling it "a tedious and horrific mess that at least gives audiences what it wants: A big croc eating people, a big shark eating people, and two gargantuan stock CGI animals battling it out for the fate of Earth. Or something."
