This turns out to be the first stage in Jake infiltrating a gang of human traffickers, run by three brothers in South London. The gang has a sister, Marie Wilson, who was once the love of Jake’s life until she left him without explanation 15 years previously. Jake gets drawn deeper and deeper into this sordid world; strangely attracted by parts of what he finds. Is he still in love with Marie, why did she leave him so suddenly and will he and his family get out alive?
