Louise Evans has recently been promoted to Customer Advisor for High Net Worth at ZBG Banking. A single mum to Erica, she’s always short of cash but is currently enjoying life with best friend Anna. Louise agrees to a night out at Anna’s boyfriend’s new bar, but definitely ends up with more than she bargained for after Phillip propositions her, offering her £10,000 if she will help him to de-fraud one of ZBG’s largest clients. Louise refuses to get involved. Drinking in the bar, a mysterious admirer (Crawford) is watching Louise and sees that she could be in trouble, so aids her escape from a toilet window. Phillip orders one of his thugs, Mickey, to go and find her. After seeing her safely home, Crawford gives Louise his number and tells her to call him if she needs him. After she closes the door, Crawford makes a telling phone call. In the flat, Erica has been kept awake by the phone ringing. Mickey has tracked her down and tells her that he’s parked outside her house and she has to come out. Mickey then tries to bundle Louise into the car, but when she struggles, he throws an envelope at her and drives away. After opening the envelope, Louise realises that Phillip is using a past fraud to blackmail her…

Tension heightens between Phillip and his business partner Manesh when Phillip realises that he has been left out of the loop regarding some important information. Ben’s feeling the pressure as security is tightened at ZBG and informs Manesh that he thought he was going to get the sack after being called into see his manager, but was merely made into a permanent member of staff. After studying her on CCTV footage, Harry Wallingford, Head of Internet Fraud, wants to arrest Louise but Crawford stops him. He has the transcript of a call from a ZBG employee at Canary Wharf, saying she is being threatened into committing fraud. Crawford convinces Harry that Louise is small fry, and that they could use her to lead them to the big fish. Crawford visits Louise’s flat and finds extremely loud music coming from inside. Louise’s neighbour tells him that it’s been like this for a couple of hours. Crawford manages to calm Louise down and they talk about Anna’s death. Could Crawford be about to make a big mistake?

Louise decides it will be safer to send Erica to live with her father. When Simon arrives to pick her up, she gives him the £15,000 that Phillip gave her as a trust fund for Erica. Arriving at ZBG Bank Crawford calls her to let her know that Hugh Borne has been found dead. He tells her that she needs to be careful because the criminals may have people watching her in the bank - she can’t trust anyone. Crawford phones Harry Wallingford to let him know that Louise is working for them now, and he needs to keep an eye on her for her own safety. Mart sends Louise to Canary Wharf to check out the transaction team for the Lewis Stone deal. On the transaction floor, Louise sees Ben and thinks she recognises him but can’t place him. As she leaves, Ben nearly bumps into her and suddenly remembers that he has seen her at the Curry House. In the Canary Wharf canteen, Louise deliberately bumps into Ben and puts a note on his tray: ‘I know about Starwatch. We need to talk.’ She shows Ben the scars behind her ears and they agree that they have to help each other.
