Kadota, a veteran tour escort working for the travel agency that organised a ‘25-day all-female tour of Europe’, sets off from Japan alongside Hijikata, who has been handpicked as the tour guide following a forceful recommendation from Egi, a travel journalist popular with wealthy ladies. Amidst a tangled web of rivalry and jealousy amongst the participants, and with the future of the tour looking uncertain, the group encounters a series of strange incidents—including a theft—at their refuelling stop in Anchorage and their first sightseeing destination, Copenhagen.
