They're looking for the driver who hit a woman on the highway. The suspect is engineer Peter Sergeev. But Sergeev, who accidentally dropped a photo of his fiancee Irina at the scene, did not commit a crime. When he saw a woman lying on the highway, he drove away so as not to get involved in the story, although timely help could have saved her.
