Thomas McGregor (Domhnall Gleeson) and his former neighbor Bea (Rose Byrne) are now married and have gotten used to living with Peter (voice: James Corden, German: Christoph Maria Herbst) and his family of rabbits spend. From then on, people and animals peacefully shared the garden. But even if Peter makes every effort to be a good roommate, he will never completely get rid of his reputation as a chaos founder and slavonic. Frustrated, Peter searches for distraction away from the garden – and promptly finds it in the big city, which offers completely new opportunities to steal vegetables with its marketplaces! When Peter also becomes friends with shady characters, he breaks up a huge mess for his entire rabbit family. But Thomas and Bea are immediately at his side to help him out of trouble, because in a real family you always stick together.
