Dont drive at night. Dont drive alone. And if you do break down, dont open the door to anyone even if you believe theyre there to help you. Theres a killer on the roads masquerading as a breakdown rescuer who strikes without warning, killing brutally with no remorse. Roaming the motorways looking for his next victim, even he doesnt know where and when his next murder will be. Andy, a young recruit to the traffic police, is determined to hunt the killer down, jeopardising his own police career in the process. After the third victim is found, he believes hes seen something crucial – but his more senior partner wont believe him. Increasingly alienated from his colleagues, Andy becomes obsessed with finding the murderer. The Searcher is an outcast from society: lonely and misunderstood, he unwittingly links Andy and the killer though his midnight searches of the motorway. As the police fail in their search for the killer and the murders continue, increasingly savage and unprovoked, Andy is determined to bring them to a halt. The action he takes brings all three together in a chilling finale.
