Investigation Discovery's true-crime storytelling is often rooted in its award-winning visuals, but it's audio from actual 911 calls that sets the tone in "Murder Calls." Each hourlong episode tracks a criminal investigation in which detectives must decipher the contents and subtext of an emergency call. As the case moves forward, the 911 audio ultimately leads investigators to the truth.
