While her father is away on a business trip abroad, Rika, the daughter of a wealthy tycoon, attempts to sneak out for some fun—but is caught by her strict maid, Keiko. Panicked, Rika tries to tie Keiko up and force her to change into casual clothes like a doll. Desperately resisting, Rika fights back, but all her efforts are in vain as she ends up subjected to Keiko's punishment.
