Synopsis
When it comes to murder, no detective starts their search at the beginning of the crime. Rather, a murder investigation always begins with the body, after the deed is done. It is up to the police to piece together the story, moving backwards in time until they arrive at the root of the crime. In REDRUM, viewers follow the backwards tale of murder from false motives and mistaken witnesses to conversations taken completely out of context, until the truth finally comes out at the very end.
