UFO HUNTERS follows the team of Bill Birnes, Kevin Cook and Pat Uskert, as they investigate UFO cases around the world. The team’s access to UFO evidence is unparalleled—and their expertise allows them to quickly identify bogus claims of UFOs. Together, they use eyewitness accounts, scientific experimentation, documents recently released through the Freedom of Information Act and footage that has never been seen on television to piece together compelling—and sometimes chilling—evidence of UFO phenomena.
