With the help of a rat and a fledgling fairy, can the overworked beauty break free from her oppressive stepfamily and find her own prince charming?
Two poor brothers wearing matching bunny suits are distracted from their lives as street performers by a mysterious young girl and a very phallic train.

Is there any way for the brothers to return to their terrestrial life, after being swept up in this bizarre world of revenge schemes, court intrigue, and time travel?
