Joshua Winter returns to England from Canada where he has been living since his father disappeared ten years earlier. He is meant to be taking up a job with a big London law firm but instead is seduced by the hedonism the city provokes in him and drifts. He falls into working for a sinister entrepreneur, Dundee, who orders Joshua to put the frighteners on a late paying customer, who dies as a result. So begins a trail of murder and deception - but is Joshua really being set up? Unknown Pleasures is at once a highly evocative portrait of London and an unsettling psychological drama.
