We are surrounded by an endless stream of infinite data, with information bombarding us from seemingly every direction. These signals, which are part of our everyday operations, help define our understanding of the Universe, and largely go unnoticed.

When a powerful radio beam originating from deep space is detected by experts on earth, some suspect it's hard evidence of extraterrestrial life; new investigations into this shocking signal might reveal the truth.

A Russian radio station has broadcast a signal nonstop since the Cold War, and no one knows why; experts use hi-tech methods to investigate what it is, and what might happen if it ever stops.

When someone picks up a radio distress call from a seven-year-old boy lost alone in the desert, authorities embark on a search-and-rescue mission to find him; as the hunt continues, the case becomes more and more mysterious.
