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还不错呀！游戏和航天部门拍的好好！本来前面已经被男女主慢悠悠的爱情进度搞的弃剧了，又被一场王者比赛和后面的航天日常给拉回来了。终于有个不成天没事干只谈爱情的剧了！但剧本着实有点弱，男女主cp感也不够强，前面那些对手戏我个人都没什么感受，反而打的那场比赛和后面两人分隔后男主独自思念女主，我终于get到了。 刚开始感受杨洋的于途太端着，但看久了感受也挺合适理工直男那种不解风情直愣的感受。ps：宇宙是真的很浪漫呀。
