The plot is thicker than the air quality at the Quarry Bank Mill as this gripping drama continues. Feisty Esther (Kerrie Hayes) is up in front of the beak for her stunt with the clapper, but can she prove that creepy overseer Charlie (Craig Parkinson) was giving her the eye? New apprentice Lucy (Katherine Rose Morley) arrives at Quarry Bank with her sister, but when Little Sis is declared unfit for work, there are heartbreaking consequences. Daniel (Matthew McNulty) is doing his brooding best, bridling against the injustices of mill life without biting the hand that's feeding him. If you haven't already, cotton on.
