Ten-year-old Takuya has a new job: to look after his baby brother Minoru...looks like it's time to put on the kid gloves! Young Takuya has it tough. Since his mother passed away, he's had to take care of his baby brother Minoru while their father works the long hours of a Japanese "salaryman." Takuya and his friends share a beach house over summer vacation and run afoul of Moriguchi's foxy grandma, who loves checking out the hot young studs at the beach...and hates looking after kids. But when Minoru and his fellow toddlers get lost in the woods, it's grandma to the rescue! Then Takuya looks after a neighbor's talking parakeet, much to the delight of Minoru. What happens when Minoru gives into the temptation to let their guest out of his cage just once?
