This is a 54 card set.
John Putnam (Richard Carlson) witnesses something crashing in the desert. He finds the wreckage of an Alien spacecraft and it seems some of the occupants have escaped. His Fiance Ellen (Barbara Rush) wants to believe him but soon realises he might be right when Aliens make copies of the townsfolk to blend in. John has to track down their lair when Ellen is taken hostage.
The story of the movie is told on the reverse of each card.
A 9 card movie character set is also available.
