When a salvage vessel pulls the Tardis aboard it is damaged; The Doctor is thrown clear somehow but Clara is trapped somewhere deep inside the Tardis; if The Doctor is to save her before she is killed by a fuel leak he must re-enter his damaged Tardis along with the three man salvage crew. Finding Clara won't be easy though; the Tardis is infinitely large and it will do what it must to protect itself
this becomes a problem when the salvage team decide to start helping themselves to parts they think might be valuable. If that wasn't enough to worry about there are strange creatures within the Tardis and they appear to be dangerous. If Clara is to be saved they will have to overcome many obstacles and as they do Clara will learn things that The Doctor would rather she didn't.
As a general rule all we see of the inside of the Tardis is the control room so like many fans I was intrigued when I learnt that this episode would show much more of the ship The problem is there is no way to really show its infinite size on television; we get lots of similar looking corridors and a handful of rooms, some more impressive than others, but nothing that makes the ship feel anything close to infinite. Given that complaint it is odd that one of the things I did like about this episode was the claustrophobic feel as they moved through the maze of corridors only to return to where they had just come from; this sense of unease was increased by the constantly rolling camera. The creatures roaming the Tardis were suitably creepy; more so when we learn their true nature and while the salvage crew weren't malevolent they weren't exactly friendly either; especially their leader who only wanted to make a profit and had played a particularly mean joke (which I won't spoil here) on one of his crew. As the episode approached the end it looked as if Clara had finally learnt why she was special to The Doctor then there was literally a reset switch ending which was a little bit disappointing. Despite these flaws I still rather enjoyed the episode though.
