Plot

In the kingdom of Illyria, second-born royal Sam argues against the monarchy with her friend Mike by performing rock music on the streets. Her older sister, Eleanor, is to succeed their mother Catherine to the throne following the death of their father and uncle. While spending the night out with Mike, Sam suddenly begins to experience an over-stimulation of her senses while at an underground concert and gets herself and Mike arrested when she sets off the fire sprinklers. The next day, she is informed by Catherine that she is to take summer school to make up for missing her history test.
