In the fourth episode of "Steal," Rhys and Zara race away from MI5, their hearts pounding as they navigate the streets. Once they're safely away from any potential pursuit, Rhys explains that he wanted to install a bug in Zara's place, but his request was blocked. He assumes that she's either working for MI5 or is on their radar as a potential problem. Zara admits that she was part of the thieves' operation and, in the eyes of the law, is very much a criminal.

Rhys believes they have common enemies and suggests they work together to take out the thieves and get the money back. He's convinced that someone on the Investment Committee was involved and could have even set up the entire operation. To figure out who, Rhys believes they need to get the meeting notes from the company network.
Since Rhys can't do his job via official channels due to MI5's involvement, he encourages Zara to use cash from now on and sets her up with a hotel room, given her house is being bugged. In exchange for this trust, Zara gives him the bloody fingerprint and explains how she did it. Eventually, Rhys leaves her for the night, sending the fingerprint over to his buddy at the lab. Rhys urges that this will all need to be kept under wraps, but he has his own problems to deal with. He's running out of time to pay his debts back, and not even his buddy at the bank will be able to bail him out.
Elsewhere, the thieves contemplate what to do with Zara and her vial. As they argue, we see that Luke is still alive but in a rough way. The thieves bring Luke downstairs and show him the video of Zara. They're convinced that he leaked intel about where their office was. As we know, given she followed the thieves back, Luke is innocent on this matter.
The thing is, Luke isn't a complete wet blanket either. He realizes there are fractures within the ranks of the thieves and zeros in on Morgan. Morgan thinks the situation has been compromised and wants out, but the others want to continue with their current plan. Luke plays on this and tries to wedge a gap in their ranks.
Returning to the office, Rhys and Fitch present their superior with the news that they've discovered the money is being kept in the Gould-Simmons account. The leak to the press, seemingly orchestrated by Yoshida, has sent everyone into a tizzy. In the midst of this chaos, Zara appears at the office and manages to persuade her way back into Lochmill's employment, where she eventually prints out the passwords. That night, as the office is cleared out, she breaks into Cartwright's computer. When Milo and Myrtle arrive late at night, clearly engaged in an affair, Zara is forced to hide by the printer. She evades suspicion and eventually checks over the notes. Apparently, in one of these Committee meetings, a decision was made to move everything into cash. Zara believes one of the investors may have deliberately fudged the numbers to make it seem riskier than it actually was. The two big names here come down to Milo and Kate.
Elsewhere, Yoshida, Fitch, and Rhys all fly out to Sir Toby Gould's estate. He claims he has no idea how the money ended up in his account but refuses to give the police any sort of leverage with checking his accounts. As far as he's concerned, there are important documents from the Ministry of Defence and it's a matter of National Security. As for the money itself, it was apparently moved out of Gould's account just 10 minutes after it arrived. Someone hacked in and took it out. Yoshida absolutely floors Gould and belittles him to the point of twisting his hand into complying. Interestingly, the accountant follows them out and explains that when the money was moved out, the thieves also took all of Gould's money as well - 147 million to be precise.
When Zara and Rhys finally reunite later that night, the former reveals what she's learned. Zara believes Kate is the mastermind here, but while she and Rhys discuss strategy, there's another angle worth considering. Remember how Rhys is swimming in debt and needs some cash? Well, he broaches Zara over the money she received for the deal. He also butters her up on the way home, listing all her credentials on his fingers. When she finds out Rhys was talking to her mum, Zara is not happy and walks away.
As she heads out for some food, she's approached by a man who sits opposite her and threatens Zara. Zara quickly figures out they're MI5 and forces her to leave with the men on the adjacent table into a taxi. As Zara steps inside, another man holds her at gunpoint.
