The Doctor and his friends find themselves in Bradgate after a harrowing experience in the TARDIS in which Barbara was possessed by a Vrij and tried to strangle Ian. The Vrij escaped and brought the TARDIS to the 16th century. As the Doctor teaches the girl, he realises she is Jane Grey, who is destined to become queen soon. He asks her why she helped him, and she states that she will help him and his friends leave, on one condition — they take her with them. Her parents want her to marry against her will.
