When Rash notices an apparent suicide is actually murder, he's promoted to trainee DC, much to the annoyance of his new detective Sergeant, Sands.
Meanwhile, Stefan is trying to gather intelligence on David Leese, the chief pharmacist for six London hospitals who's suspected of taking bribes.
As Rash's murder investigation leads him to a drug's trial in India six years previously, the two men find their worlds colliding. Can they work together to crack the case?
