Just at the moment when Murot is struggling with his infirmity, the aspiring inspector Colin Anta, who seems to be superior to him in every respect, is placed at his side. The investigation of a murder case in the neighboring apartment of a well known sports manager develops into a deadly competition, in which Murot loses his gun, car and even his assistant. Like an animal backed into a corner, Murot appears increasingly erratic and dogged in his thinking that Colin has something to hide. Only one superior, who has staked everything on Murot’s dubious fate, he believes to be on his side. However, she drops him mercilessly when Colin is found dead. Murot is now being searched for regardless of losses. He must solve the case, before his former colleagues get him. A struggle for existence, one against all, breaks out.
