The naked body of a young man – Jon Rydell, 17 years old - is found dumped in a bin. The autopsy, which reveals the presence of GHB in his system, also suggests that he has been sexually abused. As Irene and Jonny manage to trace back Jon’s friends – who he’d been bar hopping with before disappearing - they also discovered that he had been partying at Vacuum, one of the trendiest clubs in town. Meanwhile, Krister and his business partner Ola are having a small gathering with friends and families at the restaurant. During the event, Ola, who spotted Jenny and her friend Mercedes being quite bored, offers them a free pass to Vacuum.
