With a new breed of criminals -- rich and powerful people, corporations and individuals -- there is a need for a fresh take on law enforcement. Enter junior investigators Stefan Kowolski and Rash Sayyad, who come from different backgrounds but are now coming together to fight crime. Poland native Kowolski had to drop out of university due to a lack of money but received a life-changing offer from one of his lecturers - a job in the serious fraud office. Sayyad's family fled Iran after the revolution and his police-officer father's death. They were granted refugee status in the UK, where he joined the police force but has yet to achieve his dream of becoming a police detective. Now, he's struggling to get a coveted trainee detective constable position.
