When two young men, Vinny Holt and Craig Riley, are found brutally beaten and their bodies deliberately burned, Greco discovers that the violence may be connected to drugs and organised crime. The investigation soon leads to Ava Whitton, a seemingly respectable transport manager whose home contains evidence of heroin trafficking. As the detectives dig deeper, they uncover a sophisticated operation using legitimate freight transport as a cover for moving drugs across Europe.
Meanwhile, Ava finds herself trapped between the criminals she has been working for and the ruthless Alex Barton, a man determined to silence anyone who threatens his empire. With danger closing in from every direction, Greco must uncover the truth before the next victim falls.
