 The Doctor(Sylvester McCoy) decides to take Ace(Sophie Aldred) to the planet Segonax. Current home of the Psychic Circus. But previously unknown to the Doctor. His young traveling companion has an irrational fear of clowns. A fact that the Time lord chooses to ignore. The circus however is far from your ordinary run of the mill attraction. Run by the Ringmaster(Ricco Ross) and aided by the his cohorts Morgana and the sinister Chief Clown(Ian Reddington). They encourage visitors to audition and be a part of the show. An odd assortment of characters make their way to the Circus. Some willing to audition and other s not so enthusiastic. The geeky, fan boy known as Whizz Kid(Gian Sammarco). The brutish intergalactic biker called Nord(Daniel Peacock)and the untrustworthy, caddish explorer, Captain Cook(T.P. McKenna)and his traveling companion, Mags(Jessica Martin). But auditioning at the Psychcic circus carries a horrible price. A horrible price for those who fail to entertain the mysterious family of three who always sit at the back of the stalls. The revelation that something darker is taking place beneath the brightly covered veneer of the circus leads the Doctor to do is own unique brand of investigating. And what he uncovers is more than he might be able to handle. What with trying to prevent himself from having to audition. He must also contend with a whole host of loathsome horrors which include a android bus conductor, A werewolf, a gang of robotic clowns and the supernatural evil forces that are behind the Circus itself.
