Meet Grey Randall, a hard-boiled detective whose sense of humor makes it hard for him to stay strictly noir. It's 1948 in Las Vegas—the newborn Sin City—and he's just landed his first murder case. He's more at ease among the lowlifes, but his new client, a beautiful, wealthy woman, a real femme fatale, moves in the upper crust of society. Grey's hot on the trail of a killer, despite obstructive cops who don't want a private dick sniffing around and digging up secrets. And he starts getting close to the truth, but one of his suspects, Phillip Martin, AKA Mr. Big—AKA Mr. Beautiful—proves to be a man who could force Grey to reveal a dark secret of his own.
