Meg 2: The Trench (2023) Timeline Explained – Every Event in Order

Haiqi had escaped from her captivity at the Mana One reserve the night before the exploration. Despite being raised in captivity by Jiuming's team, her behavior had become increasingly erratic in recent days. When she encountered the submersible in the trench, she pursued and attacked it, eventually breaking through the thermocline barrier the crew used to try to evade her.

Foreshadowing: Haiqi's erratic behavior was noted by Jonas as a concern before the exploration even began.

Jess was revealed to be working with the mercenaries. After DJ, Mac, and Jess discovered their rescue pod had been sabotaged, Jess attempted to destroy Jonas, Jiuming, Rigas, and Meiying to prevent them from reaching safety. Her betrayal was tied to the larger mercenary operation led by Montes and Driscoll.

Foreshadowing: The sabotage of the rescue pod was discovered after the mining operation confrontation.

Montes was running an illegal mining operation in the Mariana Trench. When Jonas and the team discovered it, Montes detonated explosives to cover up his illicit operation and eliminate witnesses. He also harbored a personal grudge against Jonas from a previous imprisonment, adding revenge to his motives.

Foreshadowing: The mining operation was hidden beneath the trench, and Montes was established as a vengeful antagonist.

Montes's explosion to cover up his mining operation caused a catastrophic rupture in the trench wall. This rupture created an opening that allowed the three Megs, a swarm of lizard-like Snappers, and a massive octopus to escape from the depths into the open ocean and eventually reach Fun Island.

Foreshadowing: The explosion was meant to kill the witnesses but instead created the breach.

• creatures escape
• Snappers

Driscoll was the affluent financier supporting Jiuming's operation, but she aligned with the mercenaries led by Montes. After witnessing Jess being devoured by a Meg, Montes directed his mercenaries toward Jonas's group. Driscoll and the mercenaries arrived at Fun Island with lethal intent to eliminate the survivors, though they were ambushed by the Snappers.

Foreshadowing: Driscoll's true allegiance was revealed when she arrived with mercenaries rather than as a rescue force.

In the final confrontation, Jonas uses a helicopter rotor blade as a weapon. He maneuvers the rotor and strikes it through the head of the alpha Meg, killing the massive predator in a climactic battle on the beach at Fun Island.

Foreshadowing: The battle at Fun Island brought the action to the surface where Jonas could use available equipment.

When Haiqi pursues the submersible, the crew attempts to escape by diving deeper through the thermocline. Haiqi breaks through the barrier, and then two considerably larger Megs appear, an imposing alpha male and a smaller beta male. These three Megs engage in a mating display, which puts the crew in extreme danger as the predators focus on each other rather than fleeing.

Foreshadowing: The appearance of the larger Megs changed the situation from an escape to a mating display encounter.

• mating display
• alpha Meg
• beta Meg
• Haiqi

After the battle concludes, Jiuming speculates that Haiqi might be pregnant because she recently engaged in a mating display with the alpha and beta male Megs. This suggests the possibility of future Megalodon offspring, though Jonas dismisses the thought for the moment as they focus on surviving.

Foreshadowing: The mating display earlier in the film involved Haiqi with the two larger males.

After their vessels are compromised and the rescue pod sabotaged, Jonas, Jiuming, Meiying, and Rigas don exosuits and navigate through the creature-filled trench toward the Mana One station. They face Jess's betrayal and a fierce struggle with Montes before escaping in another submersible to the surface.

Foreshadowing: The exosuits were their only option after the pods were destroyed or sabotaged.

Meiying is the teenage daughter of Suyin Zhang, who passed away. She sneaks aboard the submersible during what should have been a routine exploration to witness the wonders of the trench firsthand, despite the dangers involved. Her presence puts her in grave danger when Haiqi attacks.

Foreshadowing: Meiying's sneaking aboard was a consequence of her curiosity and perhaps her desire to connect with her mother's legacy.
