True Detective , HBO‘s upcoming eight-episode drama series starring Woody Harrelson and Matthew McConaughey, will debut in January, the network said today. The project centers on detectives Rust Cohle (McConaughey) and Martin Hart (Harrelson), whose lives collide and entwine during a 17-year hunt for a serial killer in Louisiana. The investigation of a bizarre murder in 1995 is framed and interlaced with testimony from the detectives in 2012, when the case was reopened. The first trailer for the series will air this Sunday before the season premiere of Boardwalk Empire.
