Ice Age: Collision Course

Peaches is set to marry Julian, a kind-hearted mammoth. However, her father, Manny, disapproves of Julian, believing he is annoying and not suitable to care for his daughter.

Peaches expresses her wish to travel the world for her honeymoon. This idea is met with resistance from both Manny and Ellie, creating a rift in the family.

Diego and Shira contemplate starting their own family. They worry that their potential children would struggle to find friends due to existing fears surrounding saber-tooth tigers.

Sid is on the verge of proposing to his girlfriend, Francine, but finds himself heartbroken when she unexpectedly dumps him. This moment deepens his sense of loneliness as he reflects on his failed relationship.

During Manny and Ellie's wedding anniversary celebration, chaos ensues when asteroids, triggered by Scrat's antics, come crashing down on the herd. They narrowly escape what could have been a catastrophic event.

Buck returns to the herd after bravely returning a lost Chasmosaurus egg to its mother. He also brings back a mysterious ancient stone pillar that he uncovered during his adventures.

Buck reveals that the inscriptions on the ancient pillar suggest that past asteroid strikes caused two previous extinctions. He believes that investigating a nearby volcano could hold answers regarding the impending asteroid threat.

The cunning trio of dromaeosaurs—Gavin, Gertie, and Roger—overhear Buck and the herd's plans. Determined to defeat Buck and assert their dominance, they plot to sabotage the herd's mission.

As the herd heads toward the crash site, Buck devises a plan to gather small asteroids and launch them into orbit to divert the hazardous asteroid. They face numerous challenges in their quest.

The herd discovers Geotopia, a mythical community where ageless animals live. Here, Sid meets Brooke, a charming ground sloth, and experiences a budding romance.

Initially, Shangri Llama, the leader of Geotopia, refuses Buck's request to use their powerful crystals to avoid the asteroid's collision. The crystals are essential to the Geotopians' immortality, complicating the situation.

In a comedic turn of events, Sid accidentally disrupts Geotopia while trying to impress Brooke, which leads to the aging of its inhabitants. This incident angers Shangri Llama and raises tensions within the community.

Realizing the gravity of the asteroid threat, Sid convinces the Geotopians to prioritize saving their world over their fear of aging. This newfound unity leads the Geotopians and the herd to collaborate on a solution.

The team manages to fill a volcano with an orb made of crystal shards, which they believe can be launched into space to divert the asteroid. As they prepare for this crucial moment, they face last-minute challenges from the dromaeosaurs.

After successfully launching the crystals into space, the asteroid is diverted, averting disaster for the herd. The story concludes with Peaches and Julian's wedding, amidst Sid's joyful reunion with Brooke.
