剧情犯罪悬疑
Former Legionnaire Serge Lejeune, aka Sergei Lezhnev, works as a nurse in an ambulance crew and dreams of finding his mother, whom he hasn't heard from for thirteen years. One day, while on duty at a murder scene, Serge casually helps the police solve a complex crime. Demonstrating extraordinary analytical skills, he arouses the wary interest of more than just the police. Furthermore, his involvement in these investigations distracts him from his personal life—his relationship with Margarita is not working out.
