The epic three week event Mob City will debut this December on TNT. From the The Walking Dead's Frank Darabont comes this explosive drama, which chronicles the epic battle between Los Angeles Police Chief William Parker and mobster Mickey Cohen. The series tells the true story of a decades-long conflict between the Los Angeles Police Department and ruthless criminal elements led by Cohen, a one-time boxer who rose to the top of L.A.'s criminal world. The series is a fast-paced crime drama set in Los Angeles during the 1940s and '50s. It's a world of glamorous movie stars, powerful studio heads, returning war heroes, a powerful and corrupt police force and an even more dangerous criminal network determined to make L.A. its West Coast base.
