Back in the UK, Jejeune’s plan to protect Lindy has failed, and she has been kidnapped by his old foe, Ray Hayes. Jejeune's trusty sergeant, Danny Maik, tracks down Lindy, but there is far more to the situation than he anticipated. With Lindy in imminent danger, Maik is forced into a desperate rescue attempt. Will either of them survive? And if so, can they find their way back to each other?
