Four seasons in, Netflix’s The Killing is getting the axe in 2015. Judging from the first trailer for the final season though, the show is going out with a bang, or in The Killing terms, the biggest mystery Detective Linden (Mireille Enos) and Detective Holder (Joel Kinnaman) have faced so far. Watch the trailer, complete with moody music and gray-ish filter.

The trailer picks up some time after the events of season three, with Linden and Holder doing some damage control after their rash actions. But there’s no time to dwell on the past, as the detectives are assigned a new case. All the members of a seemingly perfect family are murdered, except for the son, Kyle Stansbury (Tyler Ross), who was shot in the head during the massacre. This is the only synopsis offered by Netflix, via RTE.
