On the final day of the annual hot spring welcome trip for new employees, a proposal is made that selected new office ladies chosen as event coordinators can stay an extra night as a special perk. Excited by the idea, the new hires enthusiastically cheer, "Let's go to the hot springs again?" and show interest in joining the after-bath banquet. However, this plan is actually a setup by senior employees—an "event to prey on the new girls." Their scheme? Sneak into the rooms of the newly hired women after they've passed out drunk and suddenly assault them.
