Showing this drama to someone trying to justify expanding the police dog unit would be a decent argument; it's not particularly substantial, yet it’s pleasant enough. The story centers on an officer named Frank (played by Tim Turner), who employs a police dog in his attempt to locate the person responsible for killing one of his fellow officers. Essentially, it unfolds as a straightforward pursuit, with the unusual element being that the investigator has a considerably more acute sense of smell guiding him. Joan Rice contributes some visual appeal, although I honestly couldn’t quite determine what her character's function was—she is portrayed as his sister. John le Mesurier and Christopher Lee also appear briefly, lending a smoothness to the proceedings. It doesn't seem like something that will stick with you for very long, but it's still agreeable enough to view.
