Venue: Arena Gliwice Location: Gliwice, Poland

KSW 83: Colosseum 2 was a mixed martial arts event that took place on Saturday, June 3, 2023 at the PGE Narodowy in Warsaw, Poland.

Ogrodowa Street in Lódz - just opposite a crowded shopping center, a state-of-the-art museum and a posh hotel - is where some of the city's poorest live, completely forgotten by the world. A heart-warming and funny portrait of people excluded from the mainstream of social life; people who might be more capable of sacrifice and love than those who pushed them to the sidelines of society.

A classic of cinema with a twist, that is, the story of how to intelligently empty the casino safe where the gambling underworld launders government money. The young team, which can't miss a trusted butler, an experienced gambler, an attractive thief and a powerful, though not always brilliant donkey, will follow in the footsteps of the aged legends of the criminal film world. And although there will be a number of unexpected obstacles and surprises along the way, the old team will help the new crooks realize the scam of all time. The gallant Kwinto will pave the way for the thieves to get into the safe, and the reliable Big Shoo will give the roulette specialist an accelerated course in poker.
