When the leads dry up and a case goes cold, there’s only one thing that keeps investigators going—the hunch that Somebody’s Hiding Something. In this whodunnit documentary series, viewers join detectives as they search for the person who holds the clue that will finally blow the case wide open. 

From grieving family and friends to jilted lovers and eyewitnesses, investigators pore over every detail and discrepancy to uncover the motive for the murder—along with the reason for suppressing a key piece of evidence. It’s a real-life psychological thriller, and every episode features a genuine murder mystery that keeps armchair detectives guessing until the very last frame.
