Moving, funny and surprising, this characterful ratings-winning drama stars BAFTA winner Sheridan Smith as a down-on-her-luck office cleaner lured into the high-risk world of insider trading. Sam works every night in London’s financial centre, dreaming of a better life for her and her kids. But, with a gambling addiction and spiralling debts, she’s going under. Then she overhears an illegal trade being made. If used correctly, this lucrative stock market information could be the break she needs, but how far will she go to turn her fortunes around? Its UK debut achieved an impressive 8.5m viewers, winning its primetime slot.
