The TV series "Outsider" is a Russian detective story about a wrongly convicted police officer who tries to reclaim his good name. Lieutenant Colonel Yan Ozersky spends a year and a half behind bars for a murder he didn't commit, but manages to prove his innocence in court. However, convincing his former colleagues of this turns out to be much more difficult. He is reinstated into service, but not in his previous position in criminal investigation, rather in a "paperwork" department that deals with solving old crimes. But this doesn't deter Ozersky, as he enthusiastically takes on the job.
