Back in 1995, Rust, a decorated detective, along with his trusted partner, Martin, used to work on a homicide case that has been closed ever since. However, almost 2 decades later - in 2012, to be exact - they are called in for an interrogation. So, the two take a walk down memory lane and take the investigation through every single detail they can remember. Along the way, they open up some wounds that still hurt like all those years ago. The detectives claim you don't always have to follow the law and in some cases, you'll end up losing lives if you go blindly by the book. They had to "improvise" a bit, which makes the investigators question their true motives.
