In a charming and colorful countryside world, a mischievous rabbit named Peter, with a rebellious spirit and an unrestrained love for carrots, faces a new challenge. After the death of his father, Peter and his three sisters, Flopsy, Mopsy, and Cottontail, have made an idyllic garden the source of their happiness and the key to their survival. However, their peaceful life is threatened by the arrival of a strict new owner, Mr. McGregor, who is unwilling to tolerate the antics of this group of rabbits.
Impulsive and full of cleverness, Peter decides he won’t be pushed around without a fight and devises a plan to reclaim his home. As Peter's attempts to scare McGregor become increasingly clever and hilarious, the situation becomes complicated when he begins to attract the attention of Bea, a nature-loving artist with a heart as big as her talent. Bea becomes a bridge between the human world and that of the animals, torn between her duty to the new tenant and the special connection she feels for these adorable rabbits.
The confrontation between Peter and McGregor leads to adventures filled with laughter, action, and a message about the value of friendship and family. In the end, Peter will learn that sometimes the toughest battles are fought not only with cunning but also with a little bit of heart.
