AMC's crime drama is based on the popular Danish series called Forbrydelsen. Season one and two follows three different subplots all linked to the single murder of Rosie Larsen. Season 3 picks up a year after the close of the Rosie Larsen case. Sarah Linden is no longer a detective, she has a boyfriend, and lives and works on Vashon Island at the ferries for minimum wage. She is happy and has stopped smoking but her son lives in Chicago with his father and she won't visit him. Ex-partner Stephen Holder has moved on and has a new partner. He's calmer and wears suits now. His diet has improved, he's dating an assistant district attorney and he's studying for the sergeant’s exam. He starts out looking for a runaway girl but discovers a grisly string of murders. His case leads to one of Linden's previous murder investigations - the one that drove her into the hospital - and, in turn, draws Linden back into the detective game.
The first three seasons of The Killing aired on AMC on Sundays at 9:00 p.m. Soon after the end of season three, it was announced that Nextflix ordered a six episode fourth season to air starting August 1, 2014.moreless
