Many of the Bokuto officers arrive in the mountains for a Christmas vacation.  They try to keep the fact that they are police a secret.  A couple of country dudes hit on Miyuki and Natsumi to no avail but one almost gets "lucky" with Aoi until he finds out more that he wants to know.  When the money is stolen from Ken's safe for the trip, the guys and girls go in pursuit of criminal so they can afford to pay for the trip.
