Question 9

The passengers and crew of a London to LA 747 flight are confronted by a deadly occult danger thanks to the remains of an ancient English abbey, built over a Druid site for human sacrifices, being carried in the plane's cargo hold. This eerie made for TV mix starred Chuck Connors, Buddy Ebsen, Tammy Grimes, Russell Johnson (the Professor) and especially William Shatner. (1973)
