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.
