Mistress Katya has banished her second-in-command, Justine, to a remote dungeon, although why she's done this is a mystery. Slave Tim and aspiring dominatrix Charlotte both try to find out the answer and incur Katya's wrath for their troubles. Justine knows the answer but she's not telling. She's determined not to accept Charlotte as a dominatrix either, although there's a question mark over whether her resolve will hold. A different question hangs over the head of androgynous slave Nick. He discovers his true nature within a thrillingly strict regime of female domination and discipline.
