With a severe storm about to hit the Bokuto Precinct, Natsumi and Miyuki have their hands full with a reckless driver terrorizing the city streets. It seems to happen everytime a typhoon hits the Tokyo area. Dedicated to helping a very sick kitten, whom Natsumi has named chibi, the two policewomen try to figure out why she's sick. Then Miyuki discovers that chibi is pregnant. Meanwhile, Nakajima asks Miyuki for some help which happens to send Yoriko's gossip mill racing into overtime. That help he asks for is to enhance his motorcycle to it will work better in the rain-storm. Miyuki happens to enlist the aid of the gossip-mill, Yoriko and Natsumi into enhancing Nakajima's bike. While Nakajima is racing against the reckless driver, Miyuki and Natsumi are left cleaning up the accidents that the driver is leaving behind. This also has left the two young officers to attend to a pregnant chibi as they attempt to get the small kitten to a vet while Nakajima is left to the driver.
