After defending a space station from a Cyberman incursion, the Doctor and Jamie learn that young astrophysicist Zoe wishes to join them on their travels. To give her fair warning of the dangers she may face, the Doctor places the TARDIS outside time and space and uses a mind projector to share one of their most harrowing adventures... And so, Jamie is forced to relive his encounter with the Daleks at their most evil and calculating. In a complex plot that dragged him from modern-day London to Victorian times and finally to the Dalek world of Skaro, he endured ordeals that tested his courage, strength - and his friendship with the Doctor - to the limit. He presents his own version of some of those events to Zoe; events that still anger him. And while fact and fiction blur inside the TARDIS, a malevolent force watches from without. Soon, Jamie finds himself lured from the safety of the ship into dangers that could end Zoe's travels before they begin - and all their lives, as well.
