There's something very odd about Mrs Gillyflower's Sweetville mill, with its perfectly clean streets and beautiful people. There's something even stranger about the bodies washing up in the river, all bright red and waxy. When the Doctor and Clara go missing, it's up to Vastra, Jenny and Strax to rescue them before they too fall victim to the Crimson Horror!
