The TARDIS lands in London on Christmas Eve, 1851 and almost immediately the Doctor hears his name being called. When he meets the woman shouting for him she fails to recognise him and continues calling until another man arrives and claims to be the Doctor and acknowledges the woman, Rosita, as his companion. The Doctor then attempts to help the newcomer lasso a man-size dog-like creature which has a cyber-mask, but it drags them both through the upper floor of a warehouse until Rosita cuts the rope, saving them both from plunging through a high window. The newcomer explains he has lost his memory, and the Doctor assumes he is a later incarnation, and follows him to the house of a murdered vicar, where the new Doctor says he is investigating the murder of the vicar and a teacher called Jackson Lake, and that his memory was wiped when he was attacked by the Cybermen. At the house the Doctor finds primitive memory devices called infostamps and says they have been used by the Cybermen because of the lack of technology in 19th century London. Two Cybermen attack the Doctors, but are destroyed when the new Doctor sets off a feedback loop in one of the infostamps, something he said was the cause of his memory loss. The new Doctor takes the Doctor back to his base, in the stables of an Inn, and shows him his TARDIS, a balloon (Tethered Aerial Release, Designed In Style). The Doctor finds another infostamp in the new Doctor's luggage, this one filled with information about him, and concludes that the new Doctor is really Jackson Lake, but his memory has been over-written with details of the Doctor's life by the infostamp, which itself may have been stolen from the Daleks. Lake's memory starts to return, and he remembers his wife being killed and his son being taken. Meanwhile, Mercy Hartigan, a workhouse matron has joined the Cybermen and had them kill the vicar so all the local gentlemen would attend his funeral; she arrives with the Cybermen to select four of them (the rest are killed) so she can have the children in their workhouses (including Lake's son) as a labour force for the Cybermen, who are building a 'CyberKing' to rule Earth. The Doctor is unable to stop the rise of the 200-foot tall CyberKing, which is controlled by a reluctantly-conditioned Miss Hartigan, but rescues the children. He then uses Lake's balloon TARDIS to get up to the CyberKing throne, where Miss Hartigan is held. He breaks her conditioning, and her human anger destroys the Cybermen. The Doctor uses the Cybermen's own time travel device to drag the CyberKing back into the Void, saving London. The danger over, Lake, his memory now returning, hires Rosita as nursemaid for his son and gets to see inside the real TARDIS, before insisting that the Doctor joins them for Christmas dinner.

影评:

1,影片最大的亮点在于人机恋中女声与男演员独角戏的配对，但这些色彩和空间的设置也为影片情绪氛围的营造起到了画龙点睛的作用。

2,爱即可以是一瞬间的事情，也可以是一辈子的事情。有人，因为寂寞而错爱了一人，更多的人，因为错爱一人，而寂寞一生。很多时候，我想爱你，却发现自己根本不可以爱你；很多时候，我想忘了你，可却发现你早已嵌入我的生命里。

3,爱的最高境界是什么？不是什么你死我活，是习惯。一个女人习惯了一个男人的鼾声，从不适应到习惯再到没有他的鼾声就睡不着觉，这就是爱；一个男人习惯了一个女人的任性、撒娇，甚至无理取闹，这就是爱；一个人会为了另一个人去改变、去迁就，这就是爱。对爱人，迁就多少，就爱了多少。

4,逃避不一定躲得过，面对不一定最难受；孤单不一定不快乐，得到不一定能长久；失去不一定不再有，转身不一定最软弱；你能找个理由难过，你也一定能找到理由快乐。懂得放下的人找到轻松，懂得遗忘的人找到自由，懂得珍惜的人找到幸福。

5,电影出场角色并不少，基本做到了各有特点。
