Time Heist, a title that portrays the story explicitly well. It's time to break into the most secure bank in the galaxy; the bank of Karabraxos. The Episode starts with the usual Doctor and Clara conversation, the build up. However the build up doesn't last very long, soon we are thrown into the thick of it when the Doctor picks up the ringing TARDIS phone. Upon answering the call they appear around a table with two others: Psi and Sabira, holding the infamous memory worm.
Sabira is a human mutant, some kind of mutant gene that causes her body to mirror another on contact. The ability is engaged through touch but can be held for however long afterwards. The mutant gene is hereditary, at least that's one assumption.
The second interesting character we are introduced to is Psi, a gamer, hacker, former prisoner and bank robber. Psi is an augmented human, supposedly a bank robber and once was caught in the act. In an interrogation he voluntarily wiped the memories involving his family and friends, to prevent them from being harmed.
A figure known as the Architect contacted them via a recording within a large metal case. Each person on the team agreed to rob the bank for their own reasons, however their minds were wiped to mask the guilt and criminal intent. Within the case was a sample of living human cells for Sailbra, upon touching them she changed into one of the banks previous customers with registered DNA.In this same scene we are introduced to two more very interesting characters: Miss Delphox and the Teller.
Miss Delphox is a very interesting antagonist. She is very passionate about her job, classy and someone who is borderline NOT a villain. She protects the bank as its head of security using the Teller, said to be the last of its species. Karabraxos struck a deal with the Teller and now uses it to sniff out intruders and criminals with its telepathic abilities. The so called contract is later defined as Karabraxos holding its mate as insurance, to insure the tellers loyalty. Delphox may be using the Teller against its will, but we all live to serve someone; or something ... right?
The Teller is not given a great deal of back story or character building other than he has a mate being held hostage and that he has very sophisticated telepathic abilities. The Teller is being forced into hibernation between hunts, when intruders are detected the Teller is awakened to sniff them out; like a sniffer dog at an airport.
They enter the bank to meet Delphox and the Teller for the first time. Sabira is the older man in front of the Doctor, the result of shape shifting from the living human cells in the case. The Teller had sniffed out a man who had criminal intentions, once it was locked on his mind the group managed to slip under the radar. The Teller scanned the man's brain before breaking down the neural pathways and synapses'; basically turned his brain to soup. The result was the man having a large dent in his head where his brain once was.
Sabira: 'What is that?'
Doctor: 'Don't know, hate not knowing.'
The Teller and Miss Delphox left the lobby and the team made their way into a safety deposit box, a small rectangular room for withdrawals. A package awaited them from the architect, a dimensional shift bomb; a device that moves an object to another plain. They descended through the hole they created in the floor before bringing the floor back as a team of soldiers entered the room.
They found another case containing 6 devices which none of them recognised however Sabira pointed out that the doctor was lying. The ensuing seen has them finding the Teller after crawling through an air duct. Sabira is seemingly killed in an attempt to escape an awakening Teller as it began to search her mind.
The Doctor, Clara and Psi found the vault they had been looking for but Miss Delphox had released the Teller into the tunnels where they were. Another case was found in which a data bank was stored along with a card with strange codes on it. The data bank allowed Psi to download the necessary data to unlock the 24 locks on the vault. The Teller was impound and in order to make it harder for the Teller, they split up.
The Teller found Clara first. It began to feel around in her mind, her screams attracted the attention of both Psi and the Doctor. In an act of faith Psi set the locks to automatically unlock and began to project a database of criminals onto a nearby wall, calling the Teller to him.
The Teller pursued him, letting Clara go. He used the same device Sabira used to save himself the pain of the Tellers mind feeding. Clara and the Doctor returned to the vault to find the final lock was atomically sealed, unbreakable; even for the Doctor. However a solar storm began interfering with the banks systems and broke the lock. It is then revealed that the Architect is indeed a time traveller and they have been sent back in time to the precise moment when the solar storm would make the bank vulnerable.
The card had the three locations of the rewards for the Doctor and Clara, Psi and Sabira. Sabira's reward was a gene suppressant, capable of killing off the mutant gene and Psi's reward was a device capable of restoring the memories he deleted of his family. However the Doctor and Clara's reward was located in Karabraxos' private vault. However on their way to the private vault the Teller found them and took them to Miss Delphox.
Miss Delphox assigned her private guards to deal with them before leaving the room. However when put up against the wall the guards began to uncuff the Doctor and Clara.
That's right; the guards were Sabira and Psi. Sabira used her shape shifting abilities to disguise herself but Psi hid behind a helmet. From here the episodes story arc really begins to unravel. The devices they used to supposedly kill themselves were in fact short range teleports which took them to a ship in orbit; where the TARDIS was located. From here they continued to the Private Vault which was being fed with Oxygen and a water supply; basic life support.
The vault wasn't just home to Karabraxos' private collection it was home to Karabraxos herself. Miss Delphox is found to be a clone of Karabraxos like the rest of the department heads. The Solar storm above is worsening and the Doctor suddenly notices something that could reveal the Architects identity.
'How can you trust someone that looks back at you out of your own eyes.'
He then writes down his number on a piece of paper and folds it over before writing on the front, 'I'm a time traveller.'
Madame Karabraxos gathers a small amount of her fortune and left the vault in a private elevator. The Doctor began to plan on the spot, something he does regularly. In order to remember what had happened he used the Teller, who had just arrived in the vault to recall his lost memories.
It is revealed that the Architect was indeed the Doctor, and the reason for the break in was to rescue the Teller and its mate. The person who called the TARDIS was Madame Karabraxos, on her death bed it seems. She asked the Doctor to erase on of her regrets, to rescue the Teller and its mate and return them to their home world.
In the end, Psi remembers his family and friends and Sabira's mutant gene is suppressed, all in all a happy ending. The Teller and its mate are released back on their home planet and Clara is returned home after another adventure with the Doctor.
'Robin' a bank, robin' a whole bank ... beat that for a date.'
