Megalodon

A new, colossal deep-sea oil rig, Colossus, is constructed by Nexecon Petroleum in the North Atlantic off the coast of Greenland. It is touted for unprecedented depth and yield, capable of extracting more oil than any rig before it. Geologists warn that the project sits atop sensitive fault lines, raising concerns about potential seismic disturbance.

Geologists express concerns that deep drilling could disturb fault lines on the ocean floor, with catastrophic potential. Their warnings create tension between ambitious extraction and environmental risk as Colossus readies for operation.

Peter Brazier, the CEO of Nexecon Petroleum, invites reporter Christen Giddings to visit Colossus to address the geologists' concerns. Christen is accompanied by cameraman Jake Thompson to document the findings.

The rig's crew remains confident that nothing bad will happen during drilling. They are skeptical of the geologists' warnings and the idea of a catastrophe.

Brazier hopes that a documented report on Colossus will prove the rig's safety systems and the region's stability for drilling. He seeks to reassure both investors and the public.

Drilling commences and a rich oil deposit is discovered beneath the seabed. The team pushes ahead, convinced the operation is progressing smoothly.

As drilling continues, the ocean floor fault ruptures, opening a portal to a mirror ocean hidden beneath the normal sea. The portal reveals a landscape and life forms that have been hidden for millions of years.

An explosion devastates the area and the Colossus drilling system collapses. The crew and engineers scramble to assess the damage and survive.

A team of engineers descends through a glass elevator to evaluate the situation inside the shattered rig. They move cautiously to identify hazards and locate any survivors.

A giant Otodus megalodon, the most powerful ocean predator, is spotted approaching the rig. The team realizes they are facing a creature larger than any seen before.

A desperate struggle unfolds as crew and geologists attempt to escape the Colossus. Several people fall victim to the beast, and the threat intensifies as they search for a safe exit.

Ross lures the monster toward an open space with a small submarine and overloads the fuel tanks, triggering a massive explosion. The blast destroys the creature and sacrifices Ross in the process.

After the explosion, another megalodon ventures into open waters and passes beneath a boat carrying Christen Giddings. She remains unaware of the looming danger beneath her.
