Masters continues her investigation into a people smuggling operation and the murder of Kelly Porterfield. Jake Clegg is the prime suspect in both, and appears to be working with Scotsman Logan Hunter, working in Glasgow. Masters accuses Clegg of murder, and he makes a formal complaint, for which she is reprimanded. Jen goes missing from her residential unit, and Masters fears she is heading for a swap with Hunter. Donnelly is assaulted by Clegg, and his car, fitted with a tracker, is abandoned. Can Masters get to Jen on time?
