Story

 * The movie begins on an island somewhere in the Atlantic Ocean, where a volcano begins to erupt. As the volcano erupts, inside the cave lies a temple, where an unknown creature is buried in rubble. The scene shows a close up of the creature's closed eye. Suddenly the eye opens. The scene then shows the movie title.
 * The eye scene zooms out to reveal a pet turtle of a ten-year-old boy named Jim Marcus, who has a fascination with reptiles. He also has YouTube accounts where he talks about reptiles, even one about why dinosaurs are truly reptiles and why dinosaurs are not related to birds (and no, Jim Marcus is not a creationist), and another video about particular reptiles that inspire legends of mythical creatures and cryptids. Jim gets ready for a school fieldtrip that's happening in two days.
 * At an unknown location in Canada, a lab is being attack by an unknown. Also, a few people in strange outfits captured the survivors of the attack.
 * Up on the sky an airplane with passengers in it almost ran into what it looks like a UFO like object. The flying object enters the mouth of a volcano somewhere in California.
 * Meanwhile at the island from the opening of the movie, a group is scientist are examining the temple inside the cave, led by an archeologist named Jack Albert, who identifies the structure as Atlantean. He even mentions that the ruins found in "Godzilla King of the Monsters" where not the same as the ones on the Island but are actually Babylonian due to its texture and design are different from this island. Another person examining the area is Ling Chen (the sister of Doctor Ilene Chen) about the paintings on the temple wall showing pictures of the Atlanteans having a guardian kaiju who they call Gamera. One of the paintings of Gamera's shell surrounded by flames baffles her because she doesn't understand what it means.
 * A serpent like creature starts surfacing from the ocean and heads towards the California shoreline. At a Monarch secret laboratory in California both Jack and Ling get a notification form the monitor screen about the serpent like kaiju reaching the California shoreline. Ling recognizes the creature as Garasharp, but notices that this Garasharp is acting weird but also has weird horns on her heard that are different from horns that Garasharps are supposed to have. Jack orders one of the head Monarch soldiers to evacuate as many civilians as possible from Garasharp's attack. As Garasharp attacks the city, Monarch soldiers use hi-tech weapons against Garasharp, while other Monarch soldiers do their best to take the citizens to safety. A few Monarch soldiers help lead a group of school kids (that Jim is in) to one of the Monarch shelters but struggle due Garasharp's rampage.
 * Near the city a hill of some kind starts to erupt with lava coming out of it. A giant hand comes out of the ground. Shortly after a giant hand slowly comes out of the ground with lava covering its head. Garasharp starts to notice the unknown kaiju. Both Jack and Ling have noticed the unknown kaiju from the air drones. Ling recognize the unknown kaiju as the same one from the paintings in the Atlantean ruins called Gamera. Garasharp roars at Gamera. Gamera roars back at Garasharp. Garasharp slithers towards Gamera. While Gamera crawls out of the ground on all four. While being taken to the shelter, Jim can see the two Kaiju battling out and has hope that Gamera could win the fight because of his knowledge of reptiles. As the battle between the two kaiju brings them to the city, Gamera starts to slowly comes on all two and gets the upper hand against Garasharp. Garasharp is forced to retreat. Gamera goes down on all fours and retreats into his shell. Four jets of flame come out of Gamera's shell. Gamera's shell starts floating up in the air and starts spinning as Gamera leaves the city. Ling remembers the painting of Gamera's shell surrounded by fire and realizes what that painting means.
