Detective Inspector Fusil loves his job. But the recent Burchell case landed him in front of the Chief Constable and left a black mark on his record. His future is on the line - if he can't break the next big case that comes across his desk in a timely fashion, he can say goodbye to his future in the force. Unfortunately for Fusil, his next case takes place just after one of his best men has been transferred to another county, leaving him with the inexperienced Detective Constable Kerr. Things don't get off to a good start when Kerr's unwillingness to go above and beyond the call of duty immediately puts him at odds with Fusil's all-in approach to policing. However, after the dramatic theft of five thousand pounds' worth of gold from the T.S.S. Sandstream, the two men are forced to work together. Hunting down clues in an unrelated case, Kerr starts sniffing around the Sandstream and without knowing it, edges ever-closer to the shocking truth behind the disappearing gold. With Kerr getting dangerously close to the solving the crime, the perpetrators react quickly, framing him as a blackmailer in an attempt to distract the C.I.D from their next gold theft. Faced with charges against his newest D.C., Fusil must quickly decide if he trusts Kerr or not. Would he dare risk a man's life to catch an untouchable criminal and put his own career back on track?
