For those salivating for the next edition of True Detective, the debut date is Sunday, June 21, and there's a new teaser trailer showing all the main characters in action. The plot centers around the murder of a corrupt city manager in California which threatens to derail a huge high-speed rail project that would connect the southern part of the state with the north. Competing cops Colin Farrell, Rachel McAdams and Taylor Kitsch try to solve the case while teaming up with criminal Vince Vaughn (who was a business partner of the deceased). While creator Nic Pizzolatto says season two won't be as dark as the first go 'round—it's also not going to be a laugh riot, either... as evidenced by this moody trailer.
