Haru-chan, a normal girl in a normal town, saves a strange cat carrying a present from being overrun by a truck. In return she's going to receive lots of favors, including marriage to the crown prince of Cat Kingdom. As she finds that a bit too much, she gets into contact with the Cat Business Office. Together with CBO's owner, the Baron, she enters the Cat Kingdom to try and prevent her marriage. (StudioCanal UK)
