Lieutenant Kojak arrives in Hungary as an invited guest at a criminology conference held in Budapest. In truth, however, he is simply coming home, as he once served there as an anonymous Hungarian patrol officer. Because of his current fame, he tries to avoid the spotlight, but he offers to take on a murder case as a favor to his former boss. As a seasoned detective, he successfully solves the case - and, along the way, captures the mafia henchmen who had been hunting him, pretending romantic interest in order to get close to him.
