Rash and Sands investigate a series of burglaries on upmarket London flats. Meanwhile, the SFO are on the trail of John Malik, whom they suspect is hiding serial fraudster Daniel Lorca, wanted for conning thousands of unsuspecting pensioners out of their hard-earned savings. Rash is unwittingly drafted onto the case when Stefan decides to illegally search Lorca's uninhabited London flat. Their investigation leads them to a Turkish bath, but Stefan's eagerness to find the elusive Lorca leads to the pair ending up on the wrong side of a beating. Meanwhile, another burglary is committed, but this time the homeowner, Michael Freeland, is cuddled by two masked men. When he is brought into hospital, he is forced to undergo emergency surgery - but later dies after an overdose of IV medication. Leila, Rash's sister, is blamed for his passing.
Stefan Kowolski and Arrash Sayyad are junior investigators; both are the children of immigrants. Initially thrown together by chance and common sporting interests, they later discover that they are working two different angles of the same case. Stefan is also attracted to Arrash's sister.
Kowolski is a junior investigator with the Serious Fraud Office, while Sayyad is a uniformed constable in London's police service, with ambitions of becoming a detective. In the first case, he secures a second posting as a Trainee Detective Constable, having obtained poor reviews in an earlier attempt.
Brought together by two seemingly unrelated cases, Stefan and Rash will come up against the uber rich and powerful - corporations, individuals, governments and the new breed of criminals who hide behind legitimate facades and are guarded by lawyers.
