The Slaters have been struggling financially for some time now and Jean was instantly suspicious when Stacey suddenly acquired some spare cash and correctly guessed that her daughter must have stolen it.
Jean warned Stacey that she would get arrested and sent to prison again if she was caught stealing, but Stacey lied that the money was legit and that Martin had sent it from his job abroad.
However, Jean's warning resonated with Stacey and she received a wake-up call when her pregnant daughter Lily Slater (Lillia Turner) was attacked at school.
Reminding her of her responsibilities, she decided to return the money so that she wouldn't be sent down again.
She confessed the truth to Jean and asked for her help in distracting the office security guard so that she could put the cash back in the tin. But when she was caught in the act, the security guard offered to keep quiet about the incident if she went on a date with him.
As he tried to kiss her, Stacey assaulted him and fled the building. But she was left horrified when police officer Callum Highway (Tony Clay) asked her to come to the station for an interview.
After getting together the money to pay off Shiv, she's left stunned when he demands another £200 by the following day. But when she hesitates to give him any more money, he threatens her with violence. Will Stacey be able to get out of this situation and solve her money struggles once and for all?
