Godzilla, King of the Monsters

The film begins with a deadly battle in San Francisco, resulting in the loss of Emma and Mark's eldest son Andrew. Emma glimpses Godzilla after the fight, indicating the presence of Titans. The aftermath leaves the family grieving and emotionally scarred by the destruction.

Following the events, Mark and Emma are separated; Emma works as a paleobiologist for Monarch, while Mark tries to stay connected with Madison. Emma's focus shifts to studying Titans and developing communication devices like the Orca. Meanwhile, Mark remains involved due to his concern for Madison's safety.

Emma and Madison visit an underground facility where Mothra is born. Emma manages to activate the Orca device, calming Mothra and allowing Madison to approach her. Their moment is interrupted when eco-terrorists attack, killing scientists and kidnapping Emma and Madison, with Mothra escaping.

At a senate hearing, scientists demand that Monarch be integrated into the government. They learn that Emma and Madison were kidnapped by Alan Jonah, who seeks to use the Orca to control Titans. Monarch decides to release Godzilla to gain his trust and follow him to Antarctica.

Jonah's team finds King Ghidorah encased in ice in Antarctica. They use the Orca to communicate, but Monarch's forces clash with Jonah's team. Emma activates the explosives, freeing Ghidorah, who rises and confronts Godzilla in a fierce battle.

Ghidorah is unleashed and causes destruction after battling Godzilla. The two titans clash fiercely, with Godzilla initially defeated and submerged in ice. Ghidorah's rampage results in the death of several characters, including Dr. Graham.

Ghidorah establishes dominance over the Titans, awakening others, including Rodan, and causing worldwide destruction. Godzilla recovers and returns to battle Ghidorah, with other Titans submitting to Ghidorah's leadership, creating chaos across lands.

Mothra hatches from her cocoon and joins the fight. She communicates with Godzilla and battles Rodan, helping to turn the tide. Her sacrifice by vaporization energizes Godzilla for the final confrontation with Ghidorah.

Emma opts to stay behind and uses the Orca to attract Ghidorah toward her in Boston. While Emma is knocked out, Godzilla obtains enough energy from a nuclear pulse to fully heal and become more powerful. Emma's act sparks his final assault to defeat Ghidorah.

Godzilla fights Ghidorah in a citywide battle, with Emma contributing by broadcasting frequencies. Godzilla delivers a devastating nuclear blast that kills Ghidorah, ending his reign of destruction. The city is destroyed, but Godzilla emerges victorious.

Following the battle, Titans gather and bow before a victorious Godzilla. Humanity witnesses the rise of a new king of monsters, with Madison and Mark watching in awe. The film hints at other Titan conflicts, including Kong’s existence.

In a post-credits scene, Jonah and his team find a Ghidorah head, planning to use it for unknown purposes. The scene sets the stage for future conflicts, hinting at ongoing Titan activity and new threats.
