chunk: In 1973, sports handicapper and mafia associate Sam "Ace" Rothstein (Robert De Niro) is sent to Las Vegas to run the Teamsters Union-funded Tangiers Casino on behalf of the Chicago Outfit, which secretly controls the Teamsters, while Philip Green (Kevin Pollak) serves as the mob's frontman. Taking advantage of gaming laws that allow him to work in a casino while his gaming licence is pending, Sam doubles the casino's profits, which are skimmed by the mafia before they are reported to income tax agencies. Impressed with his work, mafia boss Remo Gaggi (Pasquale Cajano), sends Sam's childhood friend and mob enforcer Nicholas "Nicky" Santoro (Joe Pesci) and his associate Frank "Frankie" Marino (Frank Vincent) to protect Sam and the whole operation. Nicky's volatile temper soon gets him banned from every casino in Las Vegas, so he gathers his own crew and engages in independent shakedowns and burglaries instead.
