The ambulance doctor Alexey Ivanov once suffered a severe trauma - his beloved classmate was strangled right on the prom night, and the memory of this terrible incident continues to haunt him everywhere. Returning briefly on business to his small homeland, to a quiet provincial town, Alexey becomes the main suspect in a crime that he did not commit, and now he is forced to lead the search for the maniac himself – as it turned out, all these years he continued to crack down on girls, and attacks happened only during those periods when Alexey was in the city.
