In order to pursue his own "rabbit" life meaning, the young and frivolous Peter (voiced by James Corden) embarked on a journey away from home and successfully won the favor of the old man Barnabas and became the leader of the gang. Unexpectedly, he pushed his old friends who followed him into a death trap. After waking up, Peter transformed into "Cruiser of the Rabbit World" and led his companions to carry out a three-dimensional rescue operation by sea, land and air. Skydiving, underwater rescue, snow mountain speed skating, speedboat pursuit, everything is possible. In this adventure, Peter gained friendship, understood family affection, and finally achieved self-growth and became a real "Rabbit Brother".
