Aunt Clare is minding Tabitha, who is playing with a flying saucer. The toy flies outside and Aunt Clara zips it back, but it is a real spaceship and she can't shrink it. Inside, spacemen Alpha and Orvis discuss their plight. Later, Samantha tells Darrin she can't undo Aunt Clara's spell and he threatens to use a saw. Panicky, the spacemen ready their N guns. At dawn, Gladys Kravitz spots the saucer and, despite Abner's scoffing, phones the Air Force. Col. Charles Burkett and his nephew, Capt. Tugwell feel Gladys is a nut but come to check. Darrin is relieved when they accept his story about promoting a new toy but later screams for Samantha when he sees Alpha and Orvis. Samantha pops into the saucer and talks family with the spacemen, explaining that Aunt Clara is a witch, and offers them breakfast. Gladys and Tugwell spot the spacemen. She tries to stop them but Alpha sends her into a happy trance. Tugwell finds Gladys picking flowers, denying everything. Aunt Clara zaps the spacemen back as Burkett arrives. Tugwell can't produce his floppy-eared men. Gladys hands hint a tulip, scolding him not to make fun of actors. Later, Darrin muses he'd like an N gun to use on his mother-in-law.
