Former missing persons detective Leroy Wright is a sceptic who doesn't believe aliens exist, unlike true believer Max Jennifer, who is convinced his wife was abducted by such beings. Against all odds, the two find themselves forced to work with each other when, at low points in their lives, they are both recruited by Capt Ava Lafrey, a take-no-prisoners former Air Force test pilot and head of the Bureau Underground, a secret government organization investigating paranormal cases. Lafrey and her staff support Leroy and Max as they look into unexplained activity and keep Earth safe.
