Reiko Kobayakawa, having risen through the ranks as an elite employee to become a section chief at a major import distribution company, was known as a ruthless boss who showed no charm or mercy, harshly scolding any underlings who made mistakes. Her cold, domineering attitude bred resentment among her subordinates. One day, due to a mistake by her subordinate, Shiraishi, she was deceived during a business trip and ultimately raped by him. Bound by rope and forced into lewd poses, she was photographed in humiliating conditions. Blackmailed with these images, Reiko is fated to be trained like a female dog by the very subordinates she once looked down upon.
