Okay, here is a plot summary for The Croods: A New Age (often referred to as The Croods 2 in some regions), presented in English:
Plot Summary:
The film picks up years after the events of the first movie. The Crood family – Grug, Ug, Gran, and Little Grug – has settled into a comfortable life in a cozy cave, living off the land and enjoying relative peace. Grug, now more of a patriarch, seems content, and the family has even adopted a dog named Beta.
However, their idyllic existence is disrupted when they discover the existence of "The Heart of the Wild," a massive, seemingly impenetrable mountain peak believed to be the tallest and most dangerous place on Earth. Spurred by curiosity, particularly by the adventurous and slightly reckless Little Grug, the family decides to climb it.
Their journey up the mountain is perilous. They encounter various challenges, including dangerous terrain, a massive storm, and other prehistoric creatures. Along the way, they befriend a group of members of the Neanderthal clan previously seen in the first film: Thunk (Grug's old rival), his sister Igritt, and their tech-savvy, fast-talking son, Neander (or "Ned"). Ned and Little Grug quickly form a strong bond, much to Grug's annoyance.
As they ascend, they learn that the Heart of the Wild is not just high, but also holds the key to understanding the world below – particularly a mysterious "Great Flood" that many ancient creatures believe is coming. They realize their cozy cave life might be threatened.
The climax involves a dramatic confrontation near the summit, where the family must work together with their Neanderthal friends to survive a final, massive obstacle – a collapsing section of the mountain – and reach the top. They discover that the "Great Flood" is indeed a real and imminent threat, caused by the shifting tectonic plates causing the oceans to rise.
The film ends with the Croods, along with the Neanderthals, safely reaching the peak. From this vantage point, they get a terrifying, firsthand view of the rising water below. They realize they must leave their home and find a new place to live together, acknowledging that their old way of life might be over. The final scene shows them watching the sunset over the vast, changing world, ready for whatever the future holds, with the bond between the two families strengthening as they face this new, shared challenge.
