***SPOILERS*** It's when locksmith Lazslo Lubasu's, Sam Jaffe, wife Maria, Lotte Palfi Andor,found out that the letters that she was getting from her daughter back in Communist Hungary were fake and the money she sent her went to the forger Miklos Konya, Lenny Cimino, her heart broke and had her dropped dead because of it. Lazslo confronting Konya in what he did ended up gunning him down when he went for his gun in a desperate attempt to escape his fate. It was then that Lazslo found evidence that it was successful businessman Gyula Jansa, Sandor Szabo, a pillar in the New York Hungarian community that set him up and about 100 Hungarian refugees escaping from Hungery during the 1956 Hungarian uprising.
In him getting his son free passage out of Hungary it was Jansa who sold out Lazslo and his family as well as the Hungarian freedom fighters by ratting them out, where they were to cross the Hungarian Austrian border, the the Hungarian version of the dreaded KGB who ended up slaughtering them! Now with hate in his heart and revenge on his mind Lazslo is out to get Bognar and waste him if it's the last thing that he does. It's the NYPD's job to keep Lazslo from doing any more killing but being as slippery as an ell in knowing his way around the city's Hungarian community that's no easy task.
With his fellow Hungarians refusing to cooperate with the police Lazslo goes about his task to get the by now scared out of his pants Jansa and give him all that's coming to him. Seeming almost invincible the 70 or so year old Lazslo even survives being shot by Jansa's wife Pauline, Lidia Prochnicka, who just fluffed if off as if it were a bee sting before disarming her and going on his merry to gun down her fleeing husband.
***SPOILERS*** In a shoot out at the O.K Corral like ending Lazslo finally corners the elusive Jansa in a railroad yard and with the police trying to stop any farther bloodshed guns him down in a deadly crossfire, between him Jansa and the police, with Jansa ending up the polluted waters of the Hudson River just were he belonged. As for Lazslo he was both out of bullets as well as blood by then and passed away with a smile on his face knowing that he avenged the death of his wife daughter and family as well as the other 100 or so Hungarians that Jansa, in order to save his son, sold out to the Hungarian Communists.
