Follows a police officer who must retrieve an eyewitness and escort her after a cartel shooting leaves several DEA agents dead, but then he must decide who to trust when they discover that the attack was executed by American forces.

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.
