Tori and the gang are offered a week-long trip to Festus' home country of Yerba to perform for the chancellor. Their vacation is not at all like they expected, with prisoners breaking into their hotel, nasty living conditions and Andre being bitten by a vampire moth, but the gang is forced to stay and put on a show for the chancellor. However, due to a "shoe malfunction" (Tori's shoe slips off and hits the chancellor in the eye), Tori is sentenced to four years in jail for assault. The rest of the gang follows suit when trying to bail Tori out (Robbie accidentally murders the chancellor's octopus). They have a rough time in prison until Sikowitz disguises himself as an Yerbanian prison guard and, while watching Cat teach her prison gang how to dance, Tori devises a plan with another woman to sneak out of prison.
