"I'm so excited." Few other details are known, but it will be a stand-alone story unrelated to the first series, which starred Matthew McConaughey and Woody Harrelson. "I know it will be eight episodes and take around four or five months to shoot," Farrell says. "I know very little about it, but we're shooting in the environs of Los Angeles." Slate reports that the plot revolves around a corrupt businessman's murder, and that the main characters will include three police officers investigating the case. Other actors rumored to be involved in some way include, according to Rolling Stone, Elisabeth Moss, Rachel McAdams, Vince Vaughn, and Taylor Kitsch.
