For the vacationers aboard the luxury spaceship Stardust, the journey does not end on the beach of their dreams, but at the bottom of the unknown planet Ythaq. There, the fearless navigator Granit, onboard technician Narvarth, and the temperamental passenger Callista quickly attract the attention of the power-hungry Countess Ophyde and her ruthless henchmen, who certainly do not come bearing an invitation for tea. Although Granit and Narvarth manage to escape with the help of locals for the time being, Callista falls into the hands of the Countess, which she soon regrets. However, even if Callista manages to outsmart Ophyde and take her place, her troubles have only just begun. Now she rules over a palace whose rules she does not know, and within its depths lies a secret.
