Apart from the Thunderdome element, this episode shares similar themes with "The Apple." Shahna, Kirk's lovely lady jailer/trainer, was born on the planet, a product of selective breeding. She is completely naive to the concept of other worlds or another way of life. Kirk and friends set out not only to free themselves but the other thralls as well - from their slavers and, ultimately, their own innocence.
