Louise Evans (Jodie Whittaker) has recently been promoted to Customer Advisor for High Net Worth at ZBG Banking. A single mum to Erica (Helena Fox), she’s always short of cash but is currently enjoying life with best friend Anna (Charlie Brooks). Louise agrees to a night out at Anna’s boyfriend’s new bar Le Rouge, but definitely ends up with more than she bargained for after Phillip (Laurence Fox) 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 (Toby Sptephens), 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 (Micky Dacks), 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, revealing himself to be a police DCI.

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.

Next day, Crawford arrives at work – the London Police Economic Crime Unit. He updates his boss DS Stuart (Katy Cavanagh) on where they’re up to with ZBG. She’s not impressed that he made contact with Louise but tells him to go ahead with the investigation. Crawford addresses his team – he wants everything they have on the club, Phillip Manningham and on Louise Evans.

Louise decides to co-operate with Phillip in the hope of getting rid of him. She goes back to see him at the club and he tells her that he wants her to set up a new account in the name of top ZBG client Lewis Stone, and gives her a forged letter signed by Stone and a piece of paper with a password, explaining that she will get her £10,000 when she brings him proof that she has done what he has asked.

After Louise texts Phillip a picture of the new account, he sends Anna round to Louise’s flat with the money. She takes it, but makes it clear to Anna that she doesn’t want anything else to do with her.

Louise has to attend a charity auction with her boss, Mart (Jason Watkins), that’s being hosted by Lewis Stone. Anna rings her mobile but Louise keeps hanging up. Anna leaves her a message telling her not to spend Phillip’s money because there will be no way out if she does. Louise arrives home to find Phillip in her flat, playing with Erica. He makes it clear to Louise that this isn’t over, and that when he needs her he will find her.

Next morning as Louise enters ZBG bank, a news reader reports that Lewis Stone is to sell his company Stone Green Energy. Louise leaves a message for Anna – telling her that she needs to help her to get rid of Phillip, she owes her. She knocks on Anna’s office door and goes in. Anna is lying dead in a pool of blood.
