Season 3 begins one year after the close of the Rosie Larsen case (the focus of The Killing's first two seasons), with Sarag Linden (Mireille Enos) no longer working as a Seattle homicide detective. But when her ex-partner Stephen Holder's (Joel Kinnaman) search for a runaway girl leads him to discover a gruesome string of murders that may connect to a previous murder investigated by Linden, she is drawn back into the life she thought she'd left behind. The new season also stars Peter Sargaard, Elias Koteas and Amy Seimetz.
