Description: The show follows numerous investigations led by William J. Birnes and his team of experts: researcher and scuba diver Pat Uskert, mechanical engineer and MIT researcher Ted Acworth, and investigative biologist Jeff Tomlinson. In the second season, Tomlinson departed. In the third season, Acworth was replaced by mechanical engineer Kevin Cook. In each episode, the team investigates reports of unidentified aerial phenomena, including interviewing witnesses of close encounters with UFOs, USOs (unidentified submerged objects), and supposed extraterrestrial life.
